I changed to the new email in 'User Control Panel: Edit Email & Password' that worked ok. I also changed my email in my 'Profile Page: Contact Info block'. However I'm unable to change it in my 'Forum Profile Page: Contact Info: Instant Messaging'.
Shucks! How can I change my email address for everything in Sissy Kiss?
The new email address is: [EMAIL="firstname.lastname@example.org"]email@example.com[/EMAIL]
