cherie, sydney seems to be a hard town to get "together" , we did it once and it was great, but it also had a lot of "fly ins " from melbourne and brissie ! OMG just ask erhan about his mascot landing its sooooooooo funny. it was 100klm winds across botany bay !!!!!!!!!!!
so maybe you are going to have to take charge of setting a date.
in melbourne we just pick something central to transport, i think that works.
last night we were only a few blocks from flinders ( your central station)
my thinking is a meetup with just 2 people is a great meetup, i personally don't care about numbers, last night unfortunately we were to have @ 12 and it ended up as 4, but it was a GREAT night, its not all about domaining so many other topics get discussed but face to face is great.
