While we're on this topic: For those interested in joining the campaign, would you rather have more frequent openings of single slots, or slightly less frequent openings but with multiple spots open?
The former option prevents spam of the Services thread, because the latter would have more overlap (i.e. users repeatedly apply in each slot opening vs. in one mass opening). However, by opening up frequently, you are able to judge people's post quality as they develop and the circumstances between members can change.
It's a balance between favoring recruitment variety vs. favoring sanctity of the thread. I think the choice is obvious.
