What is the requirements being a mod? 
Make a bunch of accurate reports of things that violate our policies (which, for the most part, our policies boil down to staying on topic and posting topics in the correct board). Keep doing that and wait until we need an additional moderator. Theymos will then select people from the topish of the list (he will check your posting history and such to make sure that you're a good person, so being at the top of the list isn't everything). He will usually start you off on a single board. If you do well there and keep reporting posts elsewhere, he'll make you a global mod when we have a need for one.
