When you copy and paste a story into the editor, it doesn't do much if you aren't on Source mode. Well... it does, but not good things.

It is preferred largely that you use Source mode in the editor because of the fact that this wiki wants to stick with one font, one color. Pasting into Visual mode has a bad tendacy to screw this up.

It is a common mistake, but when you copy and paste into visual mode, it attaches a number of bites of formatting in the text. It can screw up other things as well.

Granted, if you simply type it up and format it in MS word, and then post it to Source mode, you'll lose your bold/underline/italics. Therefore, I recommend you do not style the text before pasting, or you use the source code in your document, then copy and paste it. Source mode keeps the formatting without adding richtext or wikitext (because it basically is wikitext, in some ways.)

These are only a few reasons, but I am sure Fatal Disease and SOMEGUY123 can give a number more.

TL;DR: DO NOT USE VISUAL MODE FOR COPYING/PASTING FROM AN EXTERNAL PROCESSOR. Use Source mode.
