A new platform for the Online Judge
Dear users and friends,

As promised in the last post, exciting news are coming. I have been working on the idea of a fresh and new platform for the Online Judge for months and months. There are many reasons for this, some of them obvious, but these are probably the main ones:

- The current platform was developed in 2005.
- It uses a very old version of Joomla, which makes maintenance a very difficult task.
- The way people uses internet services (and what they expect from them) has changed a lot in 15 years.
- The new platform MUST be Open Source.
- I'm really excited in doing it!

A very initial (still not very functional) code is already working, and should serve as the basis for it. This means that we can't use it as the production platform, but also means that most design decissions are still open.

If you are interested in contribution your ideas, requests and/or your code, please start by joining the OJudge Developers Google Group by:

- Or, sending an email to ojudge-developers+subscribe@googlegroups.com   

Also, you can start having a look to the initial code at https://github.com/TheOnlineJudge/ojudge

And then, here I am, waiting for you :D

Thanks for your help!
