I am checking in on ya to make sure you getting the most value out of this group and offer some pointers.
Use discussions like this one to communicate with each other. Every member of the group will be notified when a discussion is posted and or replied to. You can elect to not receive notifications by choosing (stop following).
When you going to have a meetup, also post and event so others can see and join you - that is if your gathering is open to other members. It also does not hurt to a blog. Stager your post so your content is available on the front page - longer.
Let me know if you need other support or have questions.
