Some questions, since this sounds like something I'd not mind writing after completing v1.2 of the Quick Account Switch hack.

If I understand correctly you're all asking for an 'introduce yourself' thread bot?

I.e. a user registers using username 'x', fills in some other information as well, possibly custom profile fields.

And the admin should be able to edit a template for the subject and body of the new message, and set the forum in which it should be posted.

Would this be posted as the new user (intro thread), or as the admin (welcome thread), or should this be a setting?

I'm also supposing this should only occur if people complete the email verification (if active) or the admin approves their account (if active), to me this makes sense as I let people verify their account and would see no point in welcome threads for possibly spoofed accounts.
