Hi, Sprayer.
Once upon a time (before my time actually) we allowed users to share email addresses.
We cannot do this anymore, it allows for easy abuse of the system.
This is why we have asked you to supply a unique email address.
Please send us an email containing your new unique address and we will try and sort this out for you.
Remember, the email address in Gravatar and AB have to match.
You will not have to wait 14 days for a new avatar as you are already a member. Only NEW AB members need to wait 14 days. OLD AB members can simply change thier email addresses.
All the best
Spare Ed
