Default Message Format ?

[sumicool7]

Well basically I am making an Anime forum so I wanted some forums to have some text in the message box as default.
Like
[Title]
[Description]

etc etc

So can anyone tell me which template should I edit and what code should I use for this to actually happen.

I have attached an image for more info

Yaldaram.com is where you get it.

Its a paid plugin there and I just wanted to edit two forums with these predefined messages.
That is why I asked for the files that have to modified for this to happen.
