Interestingly, all the mtts we have currently run are turbo [...]
That is, these are
6 minute rounds, stack 10k (100BB).

What do you guys think?
[yahoo62278, famososMuertos, iv4n, arallmuus] Would these settings be acceptable for qualifiers?
There is one more problem. BCPoker does not support passwords at the moment (in development). But I can't wait to play in the tournament.
Hypothetically, we could get around this in the following way.
1. All participants who express a desire to be added to the white list (you need to provide a BC ID) and by paying a buy-in you can join the qualification game. That is, any other user outside the list will see the qualification game but will not be able to join it.
2. Anyone can join the qualification game (by paying a buy-in), but points in the electronic table are awarded only to those who declared their participation in the tournament thread.
That is, for example, Alice took 1st place in the qualification game (10 points), and Bob took 4th place, but he gets 9 points since 2nd and 3rd place were taken by users who did not declare their participation.
