I'll do one on HTML/Web Design - but I also think this could be a team project. I'm not amazing at web design, but I do know my HTML and CSS. Maybe if someone wants to email me stuff they think I should include, I can look over a list of keywords/phrases someone thinks is important and do a google on each of them?

I could also do one on the following topics:
- User/Pass authentication
- Intro to networking
- mySQL & Stuff
- Setting up a website (hosts, ftp, troubleshooting)
