Puzzle Pirates has a fairly strict setup on ranks, but there *are* 8 of them (I think, anyway…). At least one of them (the Fleet Officer) was created because the player base wanted that sort of “middle class” rank and functionality. It’s worked out well enough, and there are a couple dozen “titles” that you can assign to players on top of the rank. They are cosmetic and informational, not “functional”. (Say, the “Cartographer” title; it gives information as to what a player *does*, but not what they can do strictly with guild functions.)

As usual, though, I’d lean to giving players more control. I’d like the ability to set access permissions and such *per player* or per “tab” as you suggest.

I’m a soloist, but I agree that good guild controls are a huge boon to a social game.
