I had a thread going in #general that I can no not reply to, what should I do?

you could share a link to the original thread here and mention the ppl you want to ask for input from the other thread

ok

You can move to #random then or to a more topic-specific channel

ah, I found one, thanks

We have enabled thread discussions in #announcements (former general) back, so you can continue that thread there.

That is a good one, to talk about the announcement itself it is great
