If you could change two things about the CodeIgniter forums, they would be...

[eluser]macigniter[/eluser]
I would also like to see a way for the author of the topic to make posts stick out more than others. Sometimes when you make important announcements they get lost in nirvana because others are replying to totally different posts. I had that happen a lot and helped me out by posting the same important post over and over again.

Also what bugs me is that some users - no offense - include waaaaay too much in the quote section making some threads very hard to read and follow. I guess, especially for ignited code and its support it would be better to have a comment section per issue and not a linear discussion.
