Could you at least post in the thread who you were before? It all gets a little confusing, not knowing if you are a newer poster or a regular with a different handle.
I do think this would help folks, but sometimes people change their names because a relative found their posts, so it isn’t always possible. But I have seen people change their names and then get upset when people don’t respond to their posts as much because everyone thinks they are a stranger. Announcing your previous name could really help that.
