Moderator Application

I wasn't sure where to post this, because there is no relevant area pertaining exactly to a question like this, but I was wondering where to apply or what you need to do to become a moderator? I've noticed a lot lately that there aren't mods online when I'm in the room. I have a lot of past and current admin experience on various groups, forums and websites, as long as a pretty good tenure on the site, and would be happy to apply. I am in the chat quite often and would be able to help often.
