I have existing website written in vb.net. It uses custom class for login/authentication and authorization of users. What I would like to do is to have YAF setup in a subfolder on the main website (www.mydomain.com/forum). I would also like to have it integrated with existing user accounts so when they sign up to my website, an account is either created in YAF or YAF can use website's user account.

Any pointers on how to achieve this are appreciated.

Thanks.
