How do I disable the "duplicate post" function?

[Marcel Lee]

I want to be able to post the exact same text over and over again in a thread without it telling me that I've made a duplicate post and I'll have to wait five minutes to re-post it; because I often make picture threads where all the text is the same but the attachments differ from post to post.

In functions_newpost.php

Find ;

// Redirect user to forumdisplay since this is a duplicate post
add above it ;

$prevpostfound = false;
