You'd be surprised how many people create accounts and don't do anything (useful) with them. We currently have over 150 registered users, but only half a dozen people have ever posted.

Janitorial status would pretty much mean the ability to approve content in the moderation and spam queues... which can, of course, be undone by another janitor or admin.

I'm fine with raising the bar to 5 or 10 posts, but it'll take us longer to get a critical mass of janitors patrolling the site.

There's only one admin (me) btw...
