This is a fairly common thread on forums; how you created your username on here. Well, the Darth needs no explanation, but the other handle Xalfrea comes from my fondness for Kingdom Hearts, at the time when II came out and I was a huge fan of the Organization XIII antagonists. Using the inspiration of the antagonists names being an anagramized version with the letter X, I took the other half of my first name, Rafael, and just switched it up.
I was going to congratulate you people for being more creative than I am, but not if you're getting your user names from goats. I've been an Anakin fan since the original ROTJ premiere.
I was still a bit of a Traviss fan when I joined up, and had been using this as an online handle for a few years. It's just a Republic Commando designation where the number is my birth year. Not a Traviss fan anymore, but have never felt like changing the name, as it has just sorta stuck.
I was JediOverlord, but I changed it slightly to include my real name (I went by some variation of Overlord on the Sci-Fi Channel's old message boards). Nowadays, on other message boards, I go by "dantheman", but here I thought going by DantheJedi would be....unique, as it were.
