Aye, I agree with Red. There are ups and downs to this function, provided we could ever get it working.
For example: It could be good for RPs. Type it up in Word, run spellcheck, paste in your post. Links and the above mentioned would be easier as well.
But then, of course, we have the not-so-nice people who could be sending out links consisting of who knows what. Perhaps it is for the better, for now, if this stays merely an idea. I'm not entirely done sorting out pros & cons yet.
