Display some text at bottom of first post in *some* forums

[Pollo]

What I'd like to do is display some predefined text, at bottom of first post (only) made by the thread starter, only in certain forums (not all). Example-ish is below...



Note: This is some sample text of what it should look like.

Try using the conditionals in templates hack.

That would be this eh? I don't have a firm enough grasp in order to do it, sad to say.
