I found old Profile and Collection and Forum Posts pages - maybe someone on the team can work on re-opening the account from there?
P.S. I do vaguely remember something on the forum a while ago where someone got their account back; unless I am thinking of something else. Will see if I can find the topic ...
Yes - that was the topic I was thinking of - so seems it is possible. When Xavier returns any time soon from holidays maybe he will read this and re-open the old account.
