Let me try my question again, this time using the proper Discourse terms. I’m re-trying because the suggestion of Solved Discourse Solved plugins leads me to believe I wasn’t clear.
We have tech-oriented topics that are aging but we want to keep the text of the OP intact. At the same time, we don’t want readers to think that the text of the OP is necessarily complete. Our idea of an elegant solution is to pin a post directly beneath the OP which will contain any updates that we come across.
Does this help clarify our need?
