i am working on many asp.net projects actually mostly about open source projects, this is the one of them and it is huge project, you can work on it once you understand it you can create anykind of web application,
but it requires (vs.net, asp.net, C# knowledge), if you want to become proffessional it is worth to spend time on it (i did hours a day), and by the time i really thanks to people who helped to this or this kind of projects...thanks
it can be downloaded the at:
