You guys never answered his question.
As it currently stands, our staff members are the regulars to the site, they are the people who as stated in your posts, are trustworthy etc etc.
We don't really go looking for staff, if we ever need some, we just post an announcement and most of the people who never previously had a chance now will and the break would allow us to get a feeling for the people who would be best for the job.
If you're looking for staff yourself, dont go posting on other sites or whatever, you will just end up with people who want a shiny badge and colored username and arent actually dedicated to the site anyway, look for the people who fit what you want who are already on your site, then you know they will be more dedicated.
