Due to some "recent issues", I think the following is necessary:
Users need a way to contact moderators through the StackOverflow website.
This is especially important for suspensions, where there is no way to appeal or discuss the suspension from within SO itself.
Basically, there would be some kind of a box on the user's page that allows them to mention something to the moderators and some way to read the replies. (Or they could just go to the user's email.)
