'Invalid email address' user group

[criscokid]

Instead of changing a users primary group to 'Invalid email address' it's probably better to assign 'Invalid email address' as a secondary group.

Then when a user changes his email address his primary group will be changed to 'awaiting confirmation' (as per normal). It's at this point, when the primary usergroup is changed) that the code could be altered to drop the secondary group of 'Invalid email address'.

I think this logic is better... now all I need is someone with some coding knowledge - anyone able to assist?
