How do I start a contest?

I have seen the seaside screamer contest, and thought I might be able to do a contest like that, but haven’t seen any documentation on how to start one. Can anyone help?

Edit: I am also not very good at mapmaking, so would that hinder my efforts?

Create the rules, template, etc. and send it to one of the mods for approval.

Thanks!

Also keep in mind that it's a ton more work than you think it is to create an enticing contest, keep people motivated, explain the rules, gather entries, and then judge all the entries with good feedback. Not meaning to dissuade you, but it's a ton of work.
