I set up my profile with email firstname.lastname@example.org which is something I tend to do to aid in filtering, and as a way to detect who is to blame if I start getting spam.
But when I reply to forum replies, they come from email@example.com and the forum is interpreting that as a separate user (who isn't registered but is still allowed to post?!)
I tried to change my profile email address but it says firstname.lastname@example.org is already in use by a staged user... presumably because I replied from that address.
How can this be best resolved? My understanding is appending +... to an email doesn't make it a different address so if the software ignored it that would ideal, but can you perhaps allow both addresses for me or manually force my profile to the regular @gmail.com version and merge my posts from both?
