Hello!
As soon as you donate it sends the person you payed (the admin) an e-mail so they'll be aware of the donation and you'll get a PM shortly afterwards.
As for avatars, there are a lot of people here that make them, peanut is popular for making wonderful avatars, but if you'd like to try yourself, i saw a few peopl mention programs online that you can try, im not sure what they are though..
I use Photoshop/Imageready. If you want you can email/pm me your pictures and i can make you one as soon as i get home from work tonight.
and thanks for being a part of YT~
