I'd add only two things to bsftcs' response.

First, you don't have to go back to the warrior guild to cancel the quest. You can do that in the new guild (so you don't have to listen to the "go do your promotion quest" speech again).

Second, you cannot increase your guild level past seven. So if you're unpatched, that's the maximum number of times to go through the effort.
