Short Answer: That depends ...
That said ...
I suggest the answer to your question is: 'Yes', they should.
A new User/Patron to this "Community.FamilySearch" Forum CAN join as MANY 'Groups' in this Forum as they like (and, are ware of, of course).
Many Users/Patrons in this "Community.FamilySearch" Forum are members of MULTIPLE 'Groups' within this Forum.
New User/Patron to this "Community.FamilySearch" Forum do not need to limit themselves to being a member of only one 'Group'.
Just my thoughts.
very subjective question/answer -
but YES - why not??? its up to you.
No reason not to be part of various groups. I am a member of like 10-15.
I suspect that the only thing that might be considered a negative to joining all the groups that you are interested in is that all postings in those groups will show up in your "My Feed". The current implementation of the "My Feed" page doesn't use a topic summary approach. I.e., you can only see 2 or 3 active topics at a time. Trying to sort through all of the postings that have occurred in just the last 24 hours alone to see what might be of interest is problematic requiring you to scroll through MANY pages to see what has been going on.
Every new group that you join will exacerbate that issue. But if you have lots of time to scroll through all of those posts, then having all of those groups in your "My Feed" would be a nice way of seeing everything that is going on in all of those groups at the same time.
I would really like to see the web pages for this community evolved to use a more compact top level view of My Feed--sort of like the Feedback forum at GetSatisfaction.com/familysearch does. Instead of just 2 or 3 topics at a time that I can see in this community, in the GetSatisfaction FamilySearch forum I can scan 20 topics at a time. This could allow scanning a much larger number of groups for activity.
Jeff, Thanks for the reply. Right now several groups would probably stress me out (still in the learning process). I need to keep it simple, but in the future I know what I can do when I'm sure of what I am doing!.
Well, if you're a little curious, you can always turn them off again.
I guarantee it's easier than turning off a cell phone 😋
