Please add a function that lets users post right away and then takes them through the registration process. This will greatly increase guest to member conversion. How it could work: User reads a thread and sees the reply box at the bottom. The user decides to enter a reply, a username and password and submits A notification informs the user that an email confirmation has been sent to his email address and that the post will become visible after registration is complete. The user clicks the email confirmation link from a received email and is taken to the website. The user fills in all needed profile fields (if any) The user is taken back to the post. If the user does not complete the registration within X days, then the post is deleted.
