I'm working on a Sharepoint community site for an initiative at work and am struggling with the lack of web content management.  What I think I need is to deploy some form of wiki site or website template but I'm having trouble finding someting I can use - especially as I'm stuck using 2.0 (Sharepoint's a low priority for my organisation).

I don't have access to the server so am limited there on options, but I can upload templates through the site admin screens.  I also have zero budget so am looking for open source or free resources.

Has anyone found useful tools out there?
