There was some discussion today in the Ruby Meetup organizers call whether to keep using this google group or use the Ruby Central Discourse group. The prevailing opinion was to keep using this google group, as there's a bit of a learning curve with Discourse, and we already asked folks to join the Google Group.
If you're new to this group and happen to be seeing this through the web, note that email updates from the group will likely end up in your spam folder, so you will need to whitelist emails from the group.
