Custom Forum Solution

My site needs it's own forum! I need a full forum solution. No third party stuff if possible. I need it to be completely integrated in the site. You can see the [login to view URL] or [login to view URL] forum as an example. Guests can read forum posts but only users can write posts. The forum needs: -Complete login integration -a footer showing who is and isn't online -An RSS feed for posts -previous and next page -previous and next thread -Read/Unread icons User need the ability to: -Post text -Post links -post emoticons -reply to post -reply and quote -Remove and edit their own posts -create topics Admin/moderators needs to be able to: -delete and edit posts -ban users -write posts -create boards Posts must show: -User avatar -User post count -User interaction (PM/Comment/Add as friend/Block/view profile) -User signature User settings page also will need a forum settings option. Where users can: -Edit their signature -opt to show their last 5 forum posts on a feed in their profile. -opt to be notified when someone replies to their post. I need this completely integrated into the site's style sheet and java scripts so the forum changes with any theme editing. Examples of previous work would be great.
