Hello! Welcome to DeviantArt! I hope you have a great time here!
I know that sometimes, joining a new site can be confusing, and you probably have a lot of questions. Here is a compilation of the things most new members are confused about, and their answers: Common Questions by New DA Members
If you still have questions about how DA works, etc., feel free to let me know and I'll be happy to help with what I can.
Your gallery's looking really cool already!
Have a great day!
