My group? We wanted to turn the tavern into an adventurer's guild and worked a system out with our DM. Lines up nearly 1 to 1 with this system and we made it almost 2 years ago now.
EDIT: To make my point clear, this is more than enough information if what amounts the same thing has been serving my group for near 2 years. It's more in slightly more in depth than what we came up with while being equally understandable. At that point we were newish to DND, I think it's fine.
