The 250 offsets the 250th occurance of ' ', which therefore should be right 
after the 250th word (assuming there aren't some random occurances of it).

http://us2.php.net/manual/en/function.strpos.php - note the last example, 
where it returns 7 and not 1 (with the offset).

This function is only being used where administrators of the site would be 
inputting data, so that right now isn't a concern for me. However, once I 
get the site launched and start fine tuning my scripts, I may also put a 
character limit on it with a certain ratio of words to characters.
