It is indeed a slightly narrow rating range. And it seems to be a little bit designed so that You get to play against some higher rated players.
Personally, I never participate in no-vacation tournaments, so you lose me there. But others probably feel the opposite.
More problematic is the maximum number of participants. With so many participants, it takes far too long to fill up the tournament, and people want to get started quickly. It also takes far too long to run the tournament. Try with max 12 or 18. And be patient :-)
In addition, I think some people are intimidated by your comment: "Don't join if you plan to use all your time for every move." Why can't you use your time?
Good luck getting the tournament established!
I created a daily tournament the other day, 3-day move. I’m still the only player who’s joined. Why is this? The parameters are a little narrow but not too narrow imo; 1300-1800, 5% timeout max. Idk. https://www.chess.com/tournament/black-knights-tournament
