Looks like I got Twitter Tools working sufficiently.  Now I’m just fishing through my settings, looking for a way to widen my side bar.  Two of the items break through the right margin of it.  Do I think it will do any harm?  Not really.  It’s just aesthetically annoying.

As for the good doctor’s video, I found it helpful in setting some of the plugins up.  I’ll have to make sure I watch his videos BEFORE doing the assignments from now on. Thanks, doc!
