I guess, I should reformulate my request.

There exists the possibiliy to show the message MediaWiki:Talkpagetext to all users who edit a talk page. But

1. long-time users don't need that hint and
2. editors should see the hint, _before_ editing.

So I request the opportunity to place a small message (like "please write your message at the bottom and sign it.")

• at the top of all talk pages
• to all ip addresses and new users.

Actually I request that feature for de-wiki. But of course it would be nice to use this elsewhere, too.

Between Articletext, Noarticletext, and edit notices, I think we have enough ways to include information for users when editing. Adding anon/logged in versions of each of these would be overkill. WONTFIX.

(On a sidenote: it could be done with some site JS if the desired effect is considered an absolute must)
