Sorry for all the back and forth questions @Randy Calvert @teraßyte & @Marc Stridgen
And, thanks for all your help so far.
Here's some deeper context for what we're trying to achieve that might hopefully shed some more light on the situation (and maybe help us find a potential solution):
We have a very busy main forum and last year we noticed that there was a LOT of chatter in our main forums around specific products / vendors in our Industry.
There are about 800 different products / vendors that serve our industry and conversations around these "product / vendor" were filling up the Latest Activity feeds of members for products that they weren't interested in.
So, we decided to try and find a solution to allow our members to essentially "opt-in" to products / vendors that they were interested in seeing conversations / threads about.
To do that, one of our (ex) team members started creating Clubs with the following naming convention:
"The <Product Name> User Group"
E.g. "The Microsoft User Group", "The Kaseya User Group" etc.
Our whole goal for setting up these "User Group" Clubs like this was so that if a member was interested in say Microsoft content or Kaseya content, then they could click the JOIN button for that specific Club and immediately from that point onwards, posts / threads from inside that club would start showing up in their Latest Activity view.
(without them needing to be approved by an Admin as there is no need to stop people from joining those clubs immediately)
For people that haven't joined the Club, no posts from inside that club will show up in their Latest Activity Feed (ever).
Up until last week, we thought this system was working as originally intended.
(I personally don't use the Latest Activity view myself as I use my own Custom Streams, so I didn't know that content from Clubs I wasn't in was showing in my Latest Activity Feed)
However, last week we had a member report to us that they have been seeing posts in their Latest Activity feed from within clubs that they hadn't joined.
They originally thought it was intended behavior so hadn't reported to us before, but were wondering why it was happening.
Since then, a bunch of other members have joined in saying they are seeing it as well and so we started investigating and realized that it doesn't appear that we've set it up in the way we originally thought it would work.
(I suspect the ex team member might not have tested it properly when all the first Clubs were rolled out and our members have just "put up with it" since then until recently when some of the clubs started getting quite promotional)
So, our question here is, is there a way to have Clubs that have the following attributes:
1. They can be seen in the Club Listing by anyone who clicks on it
2. Any member can click the JOIN button and immediately be joined to the club (without requiring a manual approval process - we have 100's of clubs and 10,000+ members)
3. If a member is NOT joined to a Club, none of the posts from within that club will show in their Latest Activity feed
4. If a member DOES join a Club, from that moment onwards all posts from within that club will show in their Latest Activity feed
Any help is much appreciated 🙏
