[Foundation-l] Unable to vote

[Waerth]

It is impossible for me to vote unfortunately ..... I keep on getting 
the message:

Your Wikimedia user ID could not be determined. Please log in to the 
wiki where you are qualified to vote, and go to [[Special:Boardvote]]. 
You must use an account with at least 600 contributions before 00:00, 1 
March 2008, and have made at least 50 contributions between 00:00, 1

I am logged into nl.wikipedia, but I registered with SUL recently.
