I got an error message when entering my job posting that I have gone over the 80,000 Character Count.

If you are copying and pasting into the HTML box for the job description and you get an error message that you have gone over the character count, it is most likely not that you exceeded the 80k characters, it is most likely the outside formatting from where you copied it from.  The formatting can take up character space. 

If you do see this error message, simply cut the description out, paste it into notepad, notepad will remove the formatting and then you can paste it back into the HTML box.  This will resolve the error message.
