Hello there all of you collaborators
In the EC we don't allow previews of the strips that you are sending to your partner.
I don't know why people all of a sudden are doing this, possibly it could be a hick-up from the collaborative corpse group who allow "open collaborations".
Please follow the rules:
Basic EC in other languages
How does it work for digital art? Do they have to be printed and snail mailed?
we do not allow them as well, since there is no submission of a preview in our gallery. but if the collaborator likes to show them on his private DA gallery we can't forbid that.
