The SE network has a "protected question" feature that is justified by saying "this question is protected to avoid 'me too', 'thanks' and similar responses.
It is perfectly understandable. It is especially understandable that posting questions of similar content is definitely not allowed.
But if I want to communicate with the community (including thankful posts), I think the meta is a right place to do so. I had similar posts several times before in Space.SE and there, it was perfectly fine.
So, am I allowed to thank something, or announce anything in meta in general? Or is discussion
tag for different purposes?
