I want to set up a wiki, or possibly some other type of web-based collaboration system, and I'm trying to decide which one to use. What kind of experiences have people had with wikis on DH? Can you point me to your wiki so I can check it out? I'm thinking about using the wikipedia software because it has support for mathematical symbols, but not very many people (other than wikipedia) use it so I'm a little wary.
All thoughts on this issue are welcome.
