HitchHiker

Hi there - came across HitchHiker

it looks brilliant! But I am finding it hard to really understand how to get it to work - how even to invite people into a room I create. Tested it out with a friend who just gets "room is currently not available" message when clicking the invite link I sent... Is there a how to tutorial somewhere I could check out? Would love to use this for some teaching purposes!

Thanks a lot
