I have a front-end form that:
1) Registers a user (name, email address)
2) Creates a post
3) Sets the Post Author to the user's name
Works great. However, once the user has become registered, s/he cannot submit new posts because "This username is already registered.".
Is there a way to validate the submitter ("yes, s/he is in fact a registered user"); create a post; AND set the Post Author to this registered user's name without anyone logging into wp-admin? It seems I should be able to do this without the User Reg Add-on, but the Post Author always defaults to "anonymous" (or whomever the default author is set to).
