Do it, guys! Make your Meetup happen!
It's a great way of taking your the "virtual community" and turning it into "In Real Life community".
Start planning now for a date at least 45-60 days from now. That's about how much time you will need to plan and promote an event with a turnout of 20 RJ'rs or more.
Please let me know if I can share any experiences that can help you make your event really happen!
In the SF Bay Area, we've already had two Meetups, we have two more on the calendar with a total of 31 RSVP's, and we have "behind the scenes planning" going on for at least two more events before the end of 2013.
It's great fun doing the planning as well!
Aloha and Be Well!
