Dismissible banner on meta

Q: Is this a part of core or a plugin/component?

I want to put a similar informational note on the top of my forum. I’ve been using a house ad but i noticed it gets blocked by adblockers and is not dismissable

There is also How to create a banner


Thanks! For the record I did attempt to search to see if the question was asked but clearly not using the right keywords :woozy_face:

I think you want Welcome Link Banner


I think this is indeed a the more accurate answer to my question but the “Pin Banner Topic” method probably works best for my use case.

I really appreciate the speed and thoroughness of answers that get posted on the meta here.
