I changed to a new email adress last week.
It said it needs a week to get rid of the old one, do to security, since i dont have access to the old one.
Now I was able to change it, got a mail to it from lfs (to the new adress), pressed the link in the mail, locked into the forum with the link.
But there is still my old @aol adress, not the new one.
What can I do now?

Can you remember exactly what it said when you clicked the link in the email? It sounds like the new email address was not registered properly, but in that case I would expect something like an error message.
