Alright. I sent it to you again.
I also added one of your arts into our gallery, but you chose whether to accept it or not.
You may also join groups yourself; Simply by clicking 'Become a member' or something similar that you'll see on the top of every group page you aren't already a part off.
You can also add images to groups yourself once you become a member.
You do that by clicking 'Add to a group' button, that you'll notice somewhere below your art-work. At the right side, I think.
(I apologize if you were already aware of all of this, I just felt like I should share this info. with you just in case.)
