Hi Lois, I just posted a comment on the comment wall of the Dulcimer Therapy Group. I also posted in a discussion in the Little Dulcimers Group. Both posts immediately appeared in the main 'feed' on FOTMD's Home Page. If you post something new on the site, it usually appears in the main activity feed (except for comments on people's personal profile pages).
If you want to get notifications concerning new content in particular Groups that interest you, then read this: https://fotmd.com/forums/forum/site-questions-how-do-i/18538/new-group-follow-features-added You can also subscribe to get notifications on Forum topics you like.
Because Groups are generally more focused on special interests, they tend to have less activity than the General site forums have. As with any online forum, people tend to get back what they put in, as opposed to say watching a movie. Flurries of activity come and go in various places on our site and at any given time. Some threads or groups more than others, some members more than others.
As to scrolling 72 pages, well any site with an activity feed will require a lot of scrolling through past pages if you only visit the site once in a while and then want to review weeks' worth of activity. Facebook is even worse imho since it doesn't even utilize pages...just one bottomless Black Hole of Scroll.
Lois I notice you always seem to post about having trouble missing out on or finding old content after returning intermittently, despite being a long time member. I hope this info from Dusty and me helps in some way. Maybe if you visit more often and post more in the groups and forums that interest you, you won't need to search so hard for activity you missed. ;)
