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](http://meta.space.stackexchange.com/questions/342/why-so-many-upvotes) several [times](http://meta.space.stackexchange.com/questions/533/some-small-advertising-on-reddit) before [in Space.SE](http://meta.space.stackexchange.com/questions/381/congratulations-for-tildalwave-for-the-first-golden-badge-of-the-site) 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?
