While it is possible to paste formatted text from MS Word directly into a Wiki edit page, the results may disappoint you.

Wiki formatting is not the same as Word formatting or even HTML formatting. Some of the Word markups simply don't work. Others produce surprising behaviors, making the disply look odd. Particular problems will be found with tables, which must be completely reformatted using the [[[meta:Help:Table|Wiki|Pipe Syntax]]].

Generally speaking, you can get a preview of what your Word text will look like in a Wiki environment by copy-pasting your text into Wordpad.

When copy-pasting from Word into Wiki, be sure to preview your work before saving it. This will show you the difference between what you expect, and what the Wiki will actually display.
