Thanks! I see an "Atlantic Canada" option has been entered.
You might want to add in a few other population centres (Quebec City springs to mind) and break "Atlantic Canada" out into separate cities (Halifax folks aren't likely to meet up with those in St. John's any time soon).
Even if a region doesn't have any entries, a new visitor is likely to check their current location first. Seeing "No listings yet!" is much better than the "This isn't for you!" impression given by leaving a region out.
