Pick a location that's easy to find and set a specific date and time. If you're the organizer, select something that works for you, Tuesday, 4 pm, Heart Bar, Planet Hollywood or Brew Pub at MSS. I usually pm my cell number to those who say they are attending. Understand that you're in Vegas. Sometimes people have the best intentions of attending and "Vegas" happens. If less people attend then who post on your thread, don't take it personally.
