Today we hosted our local contest and we'd like to host it online for people who couldn't attend. We already uploaded the problems to polygon and added them to a mashup contest, which I then add to a group and works fine, I don't know if it's the best way but it works.
But we would like very much if we could add ghosts participants of the original contest. We hosted it in DOMJudge and I have a scoreboard.tsv, but I don't know what format codeforces expects and can't find it anywhere. If I try with my .tsv I get "Invalid DAT-file syntax: Can't find divider character." If you could point me to what format this expects I would appreciate it :)
