I think he's trying to say something like this:
Because the new Mystery Dungeon features wi-fi, I am asking for your opinion on a Mystery Dungeon chat room and rename the D/P chat D/P/P
and make A Pokemon Mystery Dungeon chat room.
I don't understand the underlined bits very well.
So basically I think he wants a PMD chat room.
(Rhydon, feel free to correct me if I'm wrong, I don't understand it either. It would be much easier if you typed properly.)
