Thanks you two.
I didn't get any of it.
Went ahead and added the domain to my whitelist.
Sent myself a message on my old multi-account "Arji_all" . that arrived instantly.
So I klicked on the merge account button. While I got one instantly I had to search a little to find the other one in the SpamFolder.
So now I have only one account left. That's good.
Now I'm gonna play around with my email-Adresses until I find out which one works with my freshly merged warcraftpets - account and then I'll send you a message again

** Edit ** I do get the mails from the site, when I change my email. But I don't get anything, when I try to send myself a message.
Lysi, did you receive a message from me?
