Newspro has a feedback type script already for it called Ktalk but its full of bugs and hard on the server...but I'm sure you already have seenand tested this.
A ubb intergrated hack would really be great, I never did see one for the v5 series only the slashcode hack which is not what people are looking for I think.
Are these 2 different hacks or the same one I am thinking of here?
Either way a newspro/ubb comment thread hack would be great.
