Just to bump this back up to the top here.. This is still an ongoing issue in the subforum. Even on Black Friday/Cyber Monday week, there are about 10 old expired threads still taking up room on the first page with discussions about things bought several years ago. I'd like to revisit two points:
1. Having an Expired tag is only good when people actively tag their posts as expired, which most are not.
2. The posts are still getting bumped to the top of the group, regardless of being tagged Expired or not. I really suggest they get moved into either a sub-forum, or a parallel forum so that the discussion can continue but no longer clutter up.
I only really check this group once or twice every couple of months, just because it is so frustrating to actually find any good deals. I do understand that it likely requires active moderation, but I am sure that there are a handful of people around here (such as myself) who would be willing to take on that task.
