Thanks for creating the Facebook group, Robert. I don't have an account, so I won't personally be using it, so hopefully someone can relay information back here as necessary. ^_^;;
One thing that comes to mind that is different from the old group is that we no longer have an actual email list. This google group helps, a bit, but I only receive daily digests, some people only receive weekly digests, some people might not receive an email at all. And even then, the emails are generally "filter and forget," especially given the passive nature of it.
There used to be a sort of email list, as in one person had a list email addresses and would send out a reminder every week. I was doing this for a time, and even included the occasional hand-drawn comic. If anyone would like to receive these "gentle reminders" to get over to Go club at a certain time, I can start sending them out again (and maybe even include a bonus email attachment to clog up some inboxes every once in awhile).
