Ask Fedora (http://ask.fedoraproject.org) uses Askbot which is a Django based web application.   We need a few developers to implement some bug fixes and features for askbot and while upstream developers are active,  our requirements are pretty high.  So if anyone here wants to help out, please ping me offlist and I can describe the things we would like to see implemented quickly.  Some of them shouldn't take much of your time if you are a Django developer and would help our moderators and users quite a lot.
