I would like a mod where people have to pay BEFORE they can register for the site, that way I can run a private paid members-only forum. Right now, Xenforo doesn't allow this. You have to register as a guest member first, then get them to somehow "upgrade" their membership to another level. This is confusing and cumbersome, especially since there is no "free" membership level and the entire site will be paying members only. How can I move the paypal checkout scenario to be upfront at time of initial guest membership?
