Follow Me Groups Module Support
Off Topic
I think the reason you're interested in https://demo.jamroom.net/jrFollowMe/groups is because the layout is very much like meetup, but that's not because of the groups module itself but because of the design the skin has given that page.
There's a function in jamroom called {jrCore_list ....} which grabs a list of things from the database and outputs them to a skin.
So in a skin you would run a call like this:
{jrCore_list module="jrEvent" search="event_date > $now" limit=10 order_by="event_date asc" template="my_events_list.tpl"}Then you would create the 'my_events_list.tpl' file in your skin and tell it how you want to display that data eg:
{foreach $_items as $_item}
The event name is: {$_item.event_name} and its starting on {$_item.event_date}
{/foreach}
Something like that. So the concept is: Users add any event of their own to their own profile, then in the skin you suck from all of the data that each of the profiles have and display it as a list. When the site visitor clicks on the link in the list they will be taken to that items detail page on the profile of the person who created it.
