About three years ago, I registered my name as my nickname on IRC. I had to ask the staff to expire the previous registration, given the last registered 'kitt' hadn't logged in for years, they were willing to give it to me. I also followed Andy's lead and started supporting the Peer-Directed Project Center financially (mainly with a yearly subscription).
One of the nice things about registering a nickname is that, if you use it regularly, it's yours.
So, imagine my annoyance when I logged in yesterday, and someone else, someone in Amsterdam, was using my nickname. Worse, he had it as a 'KiTT' login, with a "Remember the famous car?" tagline. He wasn't relinquishing it, and I was stuck with a secondary nick name. People in the channels still knew who I was, but I wanted my nick back! I mean, isn't that the whole point of registering a nick AND supporting the network?
After being frustrated for a bit, I asked one of the staff for help.
The answer was so simple, I was embarrassed.
