Users change their usernames in their control panels?
 

Hi,
I want to know if users can change their usernames in their control panels?

I have looked around forums and only found information on old topics that this is not a feature but there are hacks to do this on vbulletin.org

But this hack is no longer downloadable!!

The reason i need this is becasue users are initally registered via Magento which uses emails as usernames, so I will need to advise users to change their usernames for security.

Is this a feature, and are there any plugins or hacks available to achieve this feature? And if not is there a reason why?

Thanks
