The Site, Gallery, Forums, Auctions, and Classifieds all use different sql databases. And while they are all on the same domain, they are not cross linkable, so that logging into one authenticates you on another. We looked into making this happen but the custom coders want around $3500.00 for each integration so I initially thought we'd put that off for awhile. Admin is doing everything she can to make you happy Bubba, but this is out of our reach for now. Hope you understand.
All you have to do is register (it just takes about 30 seconds)... then check the box to keep you logged in and I promise (as long as you keep the cookies) you will never have to worry about logging in again. I did and it works great.
