I agree that it would be nice to have a port to the Bazaar or even to Olde Town.
And yes, even a couple of other ports maybe put in our spell books, but they would have to have a level limit. I have seen too many lower rank wizards in places they should not be. Unfortunately, I don't see any way to keep them from porting to those places as they do port to higher rank wizards. Many of us don't turn off our ports because we have friends of equal rank porting to us for battle.
But the Bazaar is a good idea. The Commons seems to be the one place that some of the younger wizards get the rudest.
