uppercase sentences

Hi all, I'm working with a bunch of users who hardly ever use correct punctuation in their submitted content. I realise there's very little I can do, but I'm trying to do *something* to make things a little more presentable. At the very least, ensuring that all "sentences" begin with a capital letter (english) would be a great start. Has any one come across a library of "punctuation cleaners" or something like that? --- Justin French http://indent.com.au
