Our website has three types of groups: area groups, support groups and member organized groups.
While a member can join several or none of the support groups and member-organized groups, we do want each member to be a part of one (and only one) area group.
I'd like to find a way to use rules to check to see if a member is a member of an area group and if not, display a warning/help message to them to encourage them to join an area group. Ideally, I would like to do this several times shortly after they join and then occasionally after the first couple weeks (some people who are in the process of moving to the area may not want to join a group right away and I don't want the messages to get overwhelming for that small minority).
I've been playing around in the rules module to see what I can do, but I'm not sure exactly how to check to see if they are a member of any group of the area group type -- can anyone help me with determining what conditions I have to apply to get it to check this for me? Also can I put a limit (as suggested above) on the amount of times the message shows?
Or in lieu of that, is there an easier way to accomplish this goal of ensuring that all of our members make it into one area group?
