Forum:Deleting Retired and Semi-active categories

For our user articles, we have a bunch of categories to define the user's activity. There's Retired, Inactive, Semi-Inactive, and Semi-active. I think we should delete retired, being that any user who's retired is also inactive. It also creates a lot of spam categories on articles. Semi-active should also be deleted. In order to be semi-active, a user has to be making 10-15 posts a day. That's no different than being fully active, so, I'll probably just delete that one either way. But what do you guys think about mergin the retired category with the inactive category?
