Hi there! There's no strict list of "qualifications" we use when choosing who to add to our team other than being 18+ years of age, but generally speaking, we look for people who have a longer tenure on the forums with a somewhat sizable post count, have proven themselves to be helpful and contributory members, and have a relatively clean record when it comes to warnings and infractions. We also tend to look into applicants' post history to get a feel for how they'd mesh with our current team.
We open staff applications whenever we decide as a team that we could use extra help. They'll likely open up again sometime in the next couple months.
