Finally... Apple can now see the problem with a new message showing that you may have 2 apple ID's..
the new answer and a problem presents itself with 2 Apple ID's as shown example here.
example
1. "your_appleID"
2. "your_appleID@me.com" or "your_appleID@mac.com"
how was I able to create an apple ID with my unverified Apple @mac.com email address.
The only solution for me was to verify under another emial address I have as I do not want to lose the my apple ID which is all but short of @mac.com or me.com
How I was able to do it is another question?
Personally I do not think Apple should allow apple ID's that are the beginning of an already taken @mac.com or @me.com address.
Hope this helps.
(I'm paulenz too... I have 3!!!... paulenz was my first ever .mac.com account, that I needed to login into discussions. I don't use it though managed to bring it back to life to make a post here originally before discovering the above)
Apple if you could help that would be fantastic. Did you know Adobe sorted the merging of Adober ID's. Now that should be an incentive. 😉
