(I hope this is the right place to ask this question, but no forum seemed to suit the question particularly well.)
I want to know how people handle forum and other login systems on their site. My site is not just a forum, and has its own login, profile, password changing, validation, and so on mechanisms. But most forums come with this as well. I don't want a user to have to create two accounts to use my website fully. Any ideas on how to go about handling this problem?
(in particular, I am thinking about vbulletin here, but other forum software would be good to consider)
