Hi, I understand that XenForo is very versatile in being able to be modded to do anything you want it to, so here are my question(s): Some background: I wish to set up a forum where RPers can have seperate profiles for each character and there needs to be a methodology to "link" the accounts. It would be prohibitive to ask users to create email addresses for each character and the desired effect is to permit users to actually post as their characters, and have seperate avatar(s), profiles, etc for each character and to permit users to easily switch between characters to post with without requiring a relogin. Fist: Is it possible to alter the login authentication system workflow so that only usernames are accepted, not email addresses, and to permit users to register multiple accounts under the same email? If so, how would one hook a mod into the authentication and registration workflows to accomplish this? Secondly: is there a workflow where the user credentials can be changed, 'on the fly' (OR the attribution for the post, doesn't matter as long as the result is that the post appears to be from another user) at posting time to permit users to post as another user as long as, say the email address matches between accounts? Where is this workflow and how would one hook into it? Thanks.
