I'm organizing a project in which we will create a website for a technology that may end up being open source. If it is, then we want to have a lively community.The website will include several resources, including short videos, CAD, user guides, wiring diagrams, etc.

I've never worked on an open source project before, so I'd be grateful for lots of advice and input. Specifically:

1. Best practices for creating an online community?
2. The plan is to have a wiki. I'm used to wikis, but any advice on setup/management for open source communities? (Unfortunately, it won't be Confluence.)
3. Got any great websites you recommend to check out as models?

Thanks for your help!
