Can I insert a text box (copied from Word) or do I have to use the table in the wiki? Plus, why is copying from Word so difficult? Clean??? Why?

Using a single cell table is just fine for adding a text box.

Clean MS Word HTML

MS Word is a great tool for publishing stand-alone documents. It was not designed to create good web pages.

When you copy from MS Word directly into a wiki, that's pretty much what you are doing. It's a problem all over the net, not just here.

If you really need to get stuff from Word into a wiki, try saving the Word doc as a web page (using File Save As). Then open up the resulting file in a web browser and copy that into the wiki. It still may not be perfect, but it will be better.

There are other ways to deal with using Word in a website. See these articles for more info about cleaning up Word docs for web publishing.
