Textarea maxlength with Jquery works OK but probably doesn't solve the issue of pasting in larger amounts of text.
You can truncate the contents of the textarea if it is over 150 characters as described at http://web.enavu.com/daily-tip/maxlength-for-textarea-with-jquery/. I can see some issues with copy/pasting if that brings the text over the limit though.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
