This should be an interesting journey!  As you can tell if you've viewed the blog...I'm learning by experimentation.  I really have no idea how I got my last text highlighted in red and can't figure out why everything I type is underlined when I haven't clicked the underline button!?!?!?  I guess it's a learning process and, one day I'll be able to just whip out a post in seconds, just like I want it!
