Sorry, but I´m talk about playing a private tournament that costs cents to enter. In which I see no need for a password. Try the OTR for example Diaries and search for your passwords. Several are impossible to find. I have the impression that tournaments are empty for this very reason.
Pardon me being straightforward, but
You are pretty much out of reality, common sense about this case! The ACR hosts these freerolls (they have separately their freerolls, usually in every 3 hours in the freeroll section) , but they don't finance it...
Back in the time, not so long ago, the word: 'private' was known by everyone, what the hell that can mean, its original meaning gives you the pretty basic explanation in this poker case, why they have passwords....
The money what you can possibly win there provided by the mentioned person, company whose name usually transparent even in the freerolls' names.... most of the cases, you just need to register, be a member, follow them in their online site... that's it. So it is not even that much private. From their point of view, it is like paying for any ads... What you can't find, that means, it is really private, even if you see it in the poker lobby, it is not for you. So simple....
Boy!!!! I don't get it, you come here, make a thread about it, meantime, you could go to their site, register there and it is solved out forever, within the same time (in the twitch channel cases even faster)....
