Here we go again.
It was for Nicktropolis, I loved Power Rangers at that time, and discovered that Blue was my new/permanent favourite colour hence taking a liking to the Blue Power Ranger. When registering, BlueRanger was taken, and BlueRanger1 was also. So I just chose Bluerang1 thinking it was "Bluerange1" I'm not sure if I added the "1" or not at this instance though. I only realised this error when someone on the site pointed it out, saying, "What's 'rang' anyway, is it some sort of slang?" Total realisation moment! Then, I couldn't register for Neopets on my PC for some reason, so I asked that same person who pointed out my error, not on the same day might I had, probably weeks after. She registered for me with the same Username and it's stuck ever since :) (I'll remember to save this speech whenever this question comes up again xD)
