Re: Can Tracker do m:n relations?
I should have added that you can link trackers together, such that you have a tracker that has "users" and then a tracker that has "rooms" and "desks", but again I don't think there is a way to restrict the relationship such that one row in the rooms/desks tracker can only be linked to once.
You could manage this semi-manually by changing the tracker status field of desks that are already taken, so that they would be hidden from further selection. If desks became available again then you simply change the status back.
