When I initially registered, I entered a username that was easy for me to remember. But after posting several questions and getting replies, I find that my username is a bit too close to at least one very prominent and active member. I would feel better if I could change my username.
I have been signing posts (at various points within the post) with my first name to hopefully avoid confusion.

If I register again, with a different username, can I or a moderator remove the old username?
Can a moderator have current active posts forwarded to the new registration (i'm not opposed to closing them and possibly re-opening if really needed..

Thanks,
Chris
