As Doom- pointed out this is another reason why telling people to sign up and post their pp is pointless as several people will not see that this is a catch the beat tournament, and if it wasn't for other people checking for you, you would have never noticed.
This is going to come off as harsh probably but you need to work on both your structuring of a tournament and the work you put into it as well. Maybe if you weren't trying to host 5-6 tournaments at once you would be able to focus more on making one work right. Have someone with plenty of free time work on it, as it takes effort to go through signups and make sure there are no issues there, you need map selectors for tournaments as well unless you yourself play the mode it's for enough to understand what's good for both high ranking and lower ranking players to play and what's fair for each mod pool.
Tournaments take time and a lot of effort to host right, I'm not saying you can't but it's going to be highly unlikely as long as you're splitting your attention between so many.
If you have members with a good understanding of the mode they play, maybe have them host it, I'm not going to point out everything you need to fix, as you can learn a lot by just looking at how successful tournaments are handled. I'll leave this here as an
example.
