LMAO... the cow is just my av for now because I like cows.
Threxx means... *drumroll*.... absolutely nothing!
Think about it this way. If you are in the IT industry, you will probably sign up for hundreds if not thousands of usernames for any and everything out in the internet.
Now if I just used my first initial/last name or some other common set of words, I would probably find my usual name was taken quite often, and would have to resort to some other similar name. But then when time comes to log back in I not only have to remember my password, but have to remember which of my usernames I used! True I could come up with something really long and meaningful to me that would rarely ever be taken, but I also don't feel like logging in with a super long username every time, either.
So the end result is that anytime I register for something public (like not inside a secured domain with a limited number of users) I use "Threxx". Short, simple, and never have to use another name unless I've registered there and forgot my password and no longer have the email account I was using way back when.
OK... now I gotta kill you.
Orrrrrr you can tell me WTF you've named yourself after a black female singer who needs a ghetto soldier to take care of her!
