[CB][4.5] Post/PM Word Count

[Chris]

Updates: 6/1/2008 - minimum post length no longer affects PMs 5/6/2007 - set word count enforcement to disabled by default instead of 30 words due to confusion over why submit button was disabled.

Note: If you set wordCountLimit to a number greater than 0 then the button to submit what you've typed will be disabled until the number of words specified is typed or pasted into the message box. This feature is only for sites that want their members to make posts that exceed a minimum length criteria

example:
wordCountLimit=30 means thirty words must be typed before the button to make the post enables.

If all you want is to see the number of words without requiring a minimum word length for the post then leave wordCountLimit set to zero (no editing necessary).
