Whenever I post a new thread or reply to one in my profile it shows under my user name "Fawn" how do I change that to what I want it to read? Also can a user name be changed or would I have to re-register?

I dont know about that... Mine is too.. so U should ask other people about that..

Everyone starts out as a "fawn". That will change when you've made more posts.
I may be wrong, but I don't think you can change your username without re-registering.

I finally got up to a rack Buck!!!
