How can I customize the message field with Facebook share... You used to be able able to use one of the share URLs with a ?message= parameter but that no longer works... Here is what I currently use for the contents but I can't change the users default post:
<a href="http://www.facebook.com/sharer.php?u=URL&t=TITLE">FBshare</a>
Using URL-Javascript I can alter the innerHTML of the post-field's text-area after I have gone to the URL... but I guess I can't send that information after the user has gone to the Facebook URL and left my page right?
