Topic: Verify new e-mail address
(I?m not running PUN myself for the moment so I?m not 100% sure that this feature is missing or not implemented in someway, if it?s there I apologise.)
Then a registered user changes his or her e-mail address measure should be taken to verify that it?s a correct and working address. For example the way it works in vB. Another, and maybe easier way - store the old address (address used for registration) and make it visible to moderators/admin.
In English to make Kennel happy ;)
