I think rewording the "wrong sub or you requested it" message would have soothed over some touchy new users. maybe something like "hey, chum! how's we say we move your post down the lane yander to /s/bettersubpoal

The official sub created to allow the Poal community to suggest ideas on how Poal can be improved while at the same time allowing people to comment and vote on suggested ideas.

This will make it easier for people to hear what the community has to say and to keep a record of what people wish for.

Keep your ideas short, if possible, narrow it down to one sentence. Anything longer than that will likely go unnoticed. Be straightforward.
