Hey all, just an update. There's still about 3 days to go until the submission deadline (and a further 24 hours until the publication deadline), and I've got 40 entries, which is a good start. Last year, with 3 days to go we had 42 teams, so I'm hoping there will be a comparable amount of participants. Keep the entries coming!
And regarding the questions on the formatting, yes it should be okay to just copy paste from the spreadsheet. The formatting on CN changed a couple of years ago to sometimes have those visible gridlines, and I did not think to update the original post to reflect this, I can make a note in the future. I have had problems with some entries in the past with weird formatting things, and those have always happened when it's just pasted (with grid lines), so I recommend matching the source formatting just to be safe. But also, I haven't had any issues yet this year so hopefully it'll be fine either way.
Getting excited for the season to start!
