Does something like this exist?

[AfterEffect]

I'm trying to look for some software like below, preferably open souce but that doesn't matter to much

http://www.martechsocial.com/

It's basically an all in one community site where a forum, blog, video sharing, reviews, etc are all grouped together in one site.


Probably asking a lot but does this exist? Even if I have to pay for it...
