not to hijack the thread, but to make life a little easier, highlight the text you are replying to, click ‘Quote Reply’. yes long term its time to research alternatives.
There’s a pretty easy way to deal with this: Click the “+ Reply as linked Topic” link on the right if you want to talk more about a specific restaurant. I think that’s actually much more useful than the laundry list of openings and closings followed by dozens or hundreds of replies in the same topic, even if it were threaded like before.
I’ve been using this message board system elsewhere for years, and while responses aren’t visually nested, it’s extremely robust and way more flexible than what CH is using; as long as people quote what they’re referencing or link new topics, the nesting isn’t vital.
