:Hey, there, sorry I lost track of this conversation.  I hope you're still there.  To check on the availabilty of a user name, go to http://en.wikipedia.org/wiki/Special:Listusers.  There are over 50 names beginning with some form of "Pieter", although a lot of variations would still be available.  was created yesterday.  I hope that was you, and that you can re-log in and begin using the account.  (If it wasn't you, someone must have seen this conversation and decided to be a dick about it.  You can use Special:Listusers to check any other names you want to try.)  Good luck.
