[Holbytlass]

I am who I am. I would find it hard trying to keep up with a persona on forums where I'm posting opinions and thoughts. And I wouldn't want to either. To me, that's the whole point of a user name, to freely express one's true thoughts. My user name is fun (to me) and gives others enough info to go on. I shall never be mistaken for male and it tells who I liken myself to in Middle-earth.
If someone, for some odd reason, had to do a profile on me, they could get lots of personal info from my posts. But, as HerenIstarion pointed out about people in our own lives knowing different things about us, it would be just stuff related to this forum and not everything about me.
By the way, my given name is Rebecca. Just like Gandalf, I am called many names depending who you ask.
