I have a membership site where I want new member accounts to be created by existing members.

Normally, I'd simply customize the Register single page to allow people to request their own accounts. But this client wants it to be a form that logged in members can complete.

So I've placed the register form on a page that's only available to logged in users. But when they complete the form and submit the registration, it logs them out.

Does anyone know where I would modify the registration code so that one can submit a registration without being logged out upon submission?
