Some CC maintenance is a necessary task of an owner. One item is to care for the member status, because that determines the permissions (see owner's tools).
Yes, noobs are recruits, and I leave them there until the have proven active participation in the game. Then (usually after about a month) I move them to "member". But, many of them lose interest soon and stay Recruits.
One default in the permissions is that anybody except Recruits can create tournaments. I left it that way.
As I said, I declare inactive members Recruits again. By that, newbies in probation and inactives are in the same pot. If appropriate, I select some of them to be pushed out. And if I overlooked somebody due to the bad sorting, I'm gonna find him the next time.
BTW: You will find a massive no. of inactive recruits in my CC. I leave them there for the sake of the number (200+), and there's plenty of space for new players...
