Wiki is a good way to communicate and manage knowledge, and can cooperate to share share. Unfortunately, it seems that I have not widely used. I only find Codelphi Wiki on the Internet, but it is not easy to use (it is not as SNIPSNAP.ORG, you can automatically form a directory). I don't know if 9CBS is willing to do this.
In fact, it is very small, one server and domain name, software is free.
