And the best HTML guide I've seen is Dan Mulligan's masterpiece - click here. At least, it's completely correct if viewed in MS Internet Explorer (MSIE). I haven't checked to see how it looks in Netscape. The most important thing to know about HTML here is the line breaks, [br], but in those angle brackets that are on your comma and period keys.
There's a really great way to display the HTML tags in MSIE so they look exactly like they're supposed to look when you type them - but it comes out as gibberish in Netscape. For a long time, I couldn't figure out why some people were entering line breaks in such a strange way - then I realized they didn't see things in Netscape the way I see them in MSIE.

So, class, pay attention and listen to me carefully: the end-of-the-line tag is [br], but you substitute angle brackets for the square brackets in my example.
This thread would be a nice place to practice. I'll delete extraneous practice messages after a few days.
