The following 2 examples show the difference between pasting from a plain text souce and formatting with the JCE article editor and the other is pasting from Word
Pasted from plain text
**This is the best option because you are utalizing the formatting that comes with your site so it will look unified throughout.
Pasted from MS Word
**When you paste from programs like this you are "hard coding" the formatting from Word into the article. This typically does not look the way you want it to because JCE editor and Word do not "speak the same language'. Additionally, your pages throughout your entire site will not look uniform because some may be using the template formatting and others like this will not.
