The Weekend Novelist

Some blogs have preview options which show you how it will appear, only after you preview an entry. Others, you can alternate between WYSIWG (What You See Is What You Get) and "how it looks" editing, which shows how it will actually appear )(at least, in the case of the print portion of your blog post).
Of course, there's also Flip Wilson's Geraldine character.
After all, "What you see is what you get", honey! ;)
