Step one: make a meet up group with a great crew of people. Your Melbourians with boring friends, your travellers and newbies to the city who want to explore and have fun while in this great city. Have some awesome nights at cool local bars with great specials and build a nice little group.
Step two: let anyone of the member pop up their plans for the night so they can get a bit of a crew along when they go. You know how it happens, you're sitting around sunday morning and think i could go a sunday sess, so you post it up, or come to the one someone else posted up and you go. Never again will we be bored and thinking man i wish something was happening tonight, we'll all be organisers, sans actually organising.
step one + step two = Last minute meet ups
