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!
