I'm seeking opinions on whether to run my classifieds with stand-alone user registration or to co-mingle it with my vBulletin forum user base. I'm sure that there are many pros and cons to this and I have been trying to weigh these for a couple of weeks now while testing the classifieds.
My vBulletin forum is on a separate domain name (same server) with a common interest user base of about 7,000. I realize that the users would have two different sets of cookies because of the separate domain names. On the other hand, I would need to maintain their user information file only once. My current classifieds has a separate (rudimentary) registration system.
What are other Classifieds site operators doing about integrating with a forum, or are there lots of stand-alone classifieds sites out there? Has anyone dealt with a dual domain installation before?
Truthfully, I lean toward keeping them separate. Backups are much less complex and if one system craps out, whether from error or while upgrading, the other is still rolling.
Feel free to drop me an email for discussion or comment.
Edit: It occurs to me that the registering Captcha and the ability to ban by email address or IP number might be prime motivators to use the VB
