well, those 'teachers' DID know the answers, but they fell to debating arcane technical stuff between them, and no one was sure what questions needed to be asked to get back on track. No, they were NOT trained to be trainers.
It probably would have been smoother with only one teacher. The students were mostly amateurs who didn't realize that you could run a sound system without all the details, so they tried to take it in, but were frustrated & bored..I didn't figure out the problem myself until it was almost over...and too late.

I will probably never learn the fancier aspects of HTML, but when I do decide it's time for my web page,(pictures of crafts, with explanations links), I know of helper applications like Arachnophilia which will automate and check much of the necessary basics. I do admire someone like Alice who is trying to work through some of the more complex situations and save a few $$$.

I see pages which use javascripts (or worse) to pop-up full size images from thumbnails, instead of simple links...but I see no really good reason to do this. Tables are a different matter, and I hope Alice gets her problem worked out...

(I just remembered an old sign I used to have..*grin*)

If things don't get better soon, I may have to ask you to stop helping
