It was merged into this thread:
Unfortunately merged threads stay at their original place in the forum and do not show who posted last!
However you should have gotten a note explaining what had happened to your thread!
No, I received no note. Not happy. Not happy at all.
It doesn't do any good to send a notification to someone that their thread has been merged, because there's a glitch in the notification system here. I get notifications but they're all a month or more old. If you send me a notification today about a post, it won't show up on my dashboard for about 4 weeks. It's possible others aren't receiving any notifications at all. I informed Calico about this several months ago, she said she'd let the admin team know but I was told "don't count on it getting fixed right away." (I guess they were busy getting social media publicity / tour info ready prior to release of Egypt Station.)
Just a suggestion, but until this glitch is fixed, maybe the mods can send a message to users about changes to posts through the Private Message system (like on the old maccaboard) and not use notifications.
