A Test for showing less content

This is a test post (one of many) that allows you to type away normally and then after the str_length variable has been reached it will then search for the next full stop in the posting and just display that far. This was designed to allow you to show a limited amount of content - but now i am not sure it works with Javascript very well as you cannot use brackets or quotes or anything..... hmmm... not sure on it now really. It might not work after all!
