Hey there. Welcome to PB. I'd suggest reading our rules,
here.
Posting within 60 minutes of yourself in a thread will make the forum think you're double-posting, which why
your post has all the horizontal lines through it.
And to edit your profile, go to
User CP, right after the "Welcome back, snoz1." part on the top. The options on the left sidebar let you change your avatar, signature, profile, and more.
