Yack All is a new application that lets you create a private chatroom.

I have a ton of similar tools on The Best Online Tools For Real-Time Collaboration and The Best Online Tools For Collaboration — NOT In Real Time.. In one way Yack All is less convenient than most of them because it requires registration and sign-in (though it’s extremely easy to do so).

One nice feature, though, that Yack All has but many of the others do not is that it saves the chat indefinitely.

I’ll be adding it to those “The Best…” lists because of that feature.

Thanks to Jane Hart for the tip.
