You can always continue to use dA to chat with others!
I know for a simple fact that every cool thing on here and about you means a lot to many of your friends and gives inspiration.
Personally I feel inspired when I see your amazing arts and such before too. (Kinda wish I gave a point commission to you sooner.)
If you left, I would feel deeply devastated.
But I won't stop you though from changing your mind.
If you no longer want to draw, that's okay. You don't have to draw if you don't wish to!
But please don't leave dA at the very least. Everyone would miss you. So will I.
