I read this post and spent the last few hours looking into how to make the FCKeditor not put that <p> </p> in there (instead of what I planned on working on ;-))
What I found was a way to solve it in IE but not other browsers.
By changing the /ClientScript/mojofckconfig.js like this:
FCKConfig.EnterMode = 'br'; // p | div | br
FCKConfig.ShiftEnterMode = 'p'; // p | div | br
FCKConfig.FillEmptyBlocks = false ;
(Whereas previously EnterMode was p and ShiftEnterMode was br)
I now get different bahavior in 3 browsers.
IE does what I want and puts nothing in there.
Chrome puts   but no more <p>
Firefox puts a <br /> there
So my question is should I keep these changes and have different behavior in different browsers or switch it back so its consistently <p> </p> in all browsers? Opinions?
