Contest participants were able to edit their submissions after receiving a check mark
Hi Martin, I don't know whether this was already fixed or not, so please just close if you know it's fixed.
At least two contest participants were able to edit their artwork after getting a check mark, one of them was https://inkscape.org/~Dilip/%E2%98%85dilip-about-screen-13 . One participant was not able to edit his artwork. The difference may have been in when they have tried to edit (which part of the contest).
Participants should not be able to change their drawings once they got a check.
