I just realized that I never really introduced myself to anyone, how rude

I'm new to posting, but not new to YT, I've been poking around here for quite a while. I've been looking for my puppy for a little over two years and a few months ago finally found breeders that I love. I'm picking up my baby in eight days and I am beyond excited! His name is Eli, and the picture in my avatar is him at ten weeks old. He'll be 12 weeks on Monday and waiting has been BRUTAL (as I'm sure you all know), but very worth it. I'm sure I'll have questions, and I know I'm in the right hands.
Thanks!!

Oh and also, is there any way to change my user name without creating a new account? I would like it to be puppy-related...
