I've just downloaded the thread title prefix mod here, and love it.
Though I just seem to be short of one more thing: Prefixes for the thread content. So that if people open a new thread, they "your message" part of the post, is already filled in with a basic template of what the post should contain
does this exist, or would i be able to make this work myself through coding a tad?

could i code this myself? Using the prefix mod that exists , but implementing it into the "post" part of the "new thread"
