DecalCity.com needed their Simple Machines forum integrated with their OS commerce based site. I added a forum-name field to the existing OSC account creation feature, complete with error checking. I tied together the login system, so that logging into the OSC site would create the cookie needed to log into SMF, disabled some of the forum features that would have caused problems with the system, and wrapped everything up by setting up forum accounts for the sites 9,000 existing users.
