Can we suggest future updates for this website?

I was wondering, is there some kind of forum or "contact an admin" page where we can suggest future updates or leek certain bugs that we find? Because I have a lot of really cool ideas that i think would bring in more users to this site and make it more popular. I mean I'm a programmer and a (semi)professional web page designer so I know how to spot bugs and even fix them but I'd like to see some improvements to the site more frequently than what they currently are at.
