No, I actually hadn't seen those pages. They look very useful.
I follow WikiTree's suggestion to jump in and experiment. :-) I also have a VERY basic knowledge of HTML, and that helps when it comes to working with the various formatting codes. Still, I didn't know about doing '''bold''' and ''italic'', for example, before I looked at the pages you linked.
I was actually thinking of something along the lines of a video/webinar. I think a lot of WikiTreers find the editing and merging to be a bit intimidating and think it might help.
Meantime, those pages you linked are GOOD resources than everyone should look at.
