You can go to betonanything.info and bet literally on anything you want to – like who will send you the first payment next month or whether I will keep my big mouth shut from now on.
The community there still needs to grow – so you want to tell like minded people to come. You can form your own group there too – like if you are interested in your local sports teams and have friends who are too, you can have a “pub” there that is much like your own forum, but in the shape of a messenger you can reduce and keep on your desktop while you work.
It is a really neat new application. You can use it for your own private group (nobody can enter this forum without your permission) or an open one or just participate in the general forums. And the betting functions are available to anyone for anything.
