If it's just a password, there will be many players entered who haven't qualified.
Not sure if that's the case or not, but if it is:
You should make a rule that disqualifies (and somehow punishes) anyone who registers without qualifying.
Agree.
A simpler solution would be give out token/entry to player who fullfill some ( better if public) cash game "playtrough" requirements: so only players who will qualify, therefore receiving the token in their player account, will be able to take past in this awesome satellite.
But please listen to Twitchy and forget about the password protected tourneys.
Anyway glad to read you are taking some actions to have your cash game running more often.
