I see that you have been posting other peoples art. i don't really mind of it, but here are some tips:
-remember to tell always the username of artist.
-ask the permission.
-all people don't really read the info. You could add : by (insert artist) in the end of the title.
- a folder, that says: others art, for examble.
-tell it in your profile info, that you post other artists art.
By this, you get less trouble and piss less people off.
Have a nice day\night, and welcome to deviantart!
