Crogge exist since 2005 and is used by "Markus Klimt" in Germany.
The name became quickly popular cause of private WoW Servers (He had the first private WoW Wotlk Server in public).
You can simply search a bit for Crogge and you will find a lot of interesting things, I personally really like that person cause he still care as "High" Administrator about his players.
I hope that nobody will forget him and that the Internet will keep him forever in memory, he is a interesting person and you should really have a talk with him.
The name "Crogge" has a copyright, the owner is Markus Klimt.
