Hi Johan, and WELCOME to WikiTree!
Write to info -at- wikitree.com and explain that to them. They can fix it for you.
By the way, in case it is not clear, I used "-at-" in the middle of the email address where you need to put the "at" symbol - that's the little a with a circle around it that is the upper case of the number "2" on your keypad. I did that in order to preven spammers from collecting email addresses from here - this is a public forum and anyone can see what is posted here.
I am also going to flag your question so that someone will remove your email address from it, for the same reason.
