When it comes to thinking up usernames, I hit brick walls and have a hard time coming up with anything. I originally found this site when Googling for information on how to bring my cat from the US to the UK. Being that I'm already a British national, immigration issues were not part of my picture but bringing the cat over sure was.
Well, when Google came up with the Pet section of the forums here, I started reading and posting there, and I know this is silly but for a long time I thought that was all there was to this site!! I was just very busy with the whole move at the time and the PETS process was all I had in my head, so I guess I didn't take time to peruse the rest of the boards and see that in fact it's largely devoted to immigration issues and not just how to bring a pet across too.
So I originally chose the name "Midnight's Mom" because my cat's name is Midnight and I was here to gather information for his move in addition to help from a pet transport specialist who would talk to me on the phone and always refer to me as his mom or to him as my "furry kid" (yes nauseating I know, but I can't have kids so my pet is my child.

After successfully getting through the process, I stayed here just for the conversations and to also give some help when I can on the things I've learned about in my own move, so I changed it to something less about my cat while preserving a recognition factor to others on the boards, so I just picked a random word that could be tacked onto the Midnight part, "Midnight blue" as it's a nice color and (again) I find it hard to get creative with screennames.
