Take this as a compliment, but sometimes when I see you’re already actively involved in a topic, I know it’s already in good hands so I will then just skim through it fast and not read everything 100% thoroughly or encode it to long term memory anything so I can devote my limited time elsewhere instead, so sometimes I will miss stuff.
BUT that’s not why I haven’t seen that thread before today. I apparently never even saw that thread for some reason. I assume it’s related to the issue I learned of within the last week where apparently the forum is hiding half of new posts from me (well, not hiding them, but not letting them show up as “unread”) and I can’t figure out why, so I have apparently been missing half the comments for years now.
So weird that it’s suppressing half of my unread posts including that entire thread. 
I’m glad you’ve been sharing these things when I"m absent.
