I thought that was pretty bad, if this is what I'm thinking of.

I have a better idea but I don't know if it's workable. Would it be possible to add a button or colour that people choose when posting? For instance 'Storyline' 'Trash Talk' 'Anything goes'.

That way when people are trying to post character pieces they wont get needlessly buried before they've even started, unless they actually opt for that kind of reply. Not everyone is familiar with how things work here but I think that'd be very straight forward.
