i will be installing a "QUICK REGISTRATION" application shortly and see if it helps but as it is ours is fast and u dont even need an email confirmation to sign in, most email u ur password and make u follow a link they send you in an email after u register, thats a pain in the ass especialy if the confirmation email doesnt come right away,
but we have it set up so after choosing ur user name, password and providing an email you are then able to sign in right then in there takes just minutes, but i may try the faster version soon
