Wimbledon is the highlight of the international tennis calendar. This famous championship is at its 2009 ending stage, with final matches being scheduled for this weekend.

Before you set yourselves before TVs to watch, we assume, Federer taking one more title, as well as another epic grand-slam clash between the Williams sisters, you might take a short walk through the history of the white sport in an interesting document which is to be found on doXtop. It is called Pictorial history of tennis and it`s published by our member petrol. The document is very well illustrated and it`s brief but rich in information about tennis champions. It ends with a back photo of, we think, Anna Kournikova, but we are not 100% sure.

While on topic, there is a short but quality illustrated list of The most beautiful female tennis players in our archive. We think It`s really hard to put in question autsajder`s choice.

Another fine read about the ongoing grand slam tour is Wimbledon tennis championship 2009, with adjacent comment about its technical innovation in a document called Wimbledon central court roof.

In case you play tennis even only for recreation, make sure you do not develop a painful condition called Tennis elbow, described in a document published some time ago by our member oliver.

Enjoy the Wimbledon finals! 

In case you are stil undecided about where to spend this summer holiday, here are some ideas and tips from our vast archive. Once again, we are expecting hot summer time, with soaring temperatures, which is why we are concentrating on seas, not mountains, or country side touring.

Our member Paranoid Android seemed absolutely sane when he published one of the most beautiful photo collection on doXtop to date called Beaches of the World. It`s an astonishing set of images from the most exotic sea resorts of the world, from Polynesia to Thailand and Seychelles. If money is not an issue, you`ll have a hard time choosing one of these destinations.

Another excellent document, containing descriptions and photos of European seaside resorts is called Best beaches in Europe and it was published by doXtop member trackmaster. It`s a fine collection of destinations picked and described with passion and sensitiveness.

Last but not least interesting is a short, first-hand trip report form our member hammond, who just came back from his summer holiday and published the impressions and photos in a document called Summer holiday in Croatia. Great stuff to read and watch.

We have recently presented you with our latest feature called doXtop team sites and here is a little reminder on the matter we are quite proud of.

With our team sites feature, users can apply doXtop in shortest time as external net for cross company collaboration on projects. For example, when people from different companies, organizations or any kind of business work on projects - they need to work together on documents and review, edit or expand content. Since they are situated in different locations - from streets and cities to countries and continents – their joint work is not supported by any system and they have to rely on endless e-mailing, phone calls, faxing and other forms of formal communication.

It is possible to set up an extranet and allow people to access and change data of mutual interest, but it is usually avoided in entities such as companies due to security reasons, or simply because it takes too much time and resources. True, it is also possible to use external systems such as well known social networking sites, but they do not offer adequate document management and collaboration options, which is understandable considering their entertaining and time-consuming orientation.

This is where doXtop steps in, offering what is needed for work on cross company projects. Of course, when we say “company”, take it in the widest possible meaning. It can relate to academic organizations, educational institutions, NGOs, branched businesses or societies – joint engagements of any sort.

1.  People from all over the world can collaborate on same documents through doXtop team sites.

2.  These documents can be easily uploaded, shared, edited and even versioned on our site.

3.  Documents can be published as public, private, or into Magazines, or not at all if needed so. You can only exploit our team sites feature as a tool to develop your document and then use it elsewhere. If your documents are published on doXtop - they are also automatically converted into Flash PDF or other formats. This means that readers who do not have the tools of the authors – thus cannot read the source file - now can easily read the content, its working editions and final specification.

4.  Team sites and their content are safe and protected on doXtop in a way which makes it possible to define who is allowed to access a team site, who is only a reader, an author and so on.

By using doXtop team sites, you and your colleagues can work on joint projects, documents and content creation, while sharing information with ease without technical limitations or unnecessary supervision.

In line with our policy of expanding doXtop`s presence in the world of social networking, we have enabled users to apply their Facebook data to sign up and login to doXtop.

With over 200 millions of Facebook users worldwide, we thought it would be convenient to allow them to exploit the same login data from Facebook when entering our site. This eases and accelerates the process of registering new doXtop accounts.

Don`t forget that you can embed doXtop based content into your comments on Facebook. This relates not only to single documents, but also to entire magazines, as explained in one of our previous blogs.

An Air France airliner carrying 228 people from Brazil to Paris vanished over the Atlantic today after flying into turbulence, with little hope of finding any survivors.
