Re: Email Notifications
Yes they do.
Check in "Admin > General" (I think) the option to log email sent. This way you'll know it tiki is sending the email but your host doesn't deliver it for whatever reason, or the problem is, for whatever reason, within your tiki installation.
But as I say, email notications works fine in 2.x and 3.x on most servers, as far as I know.
