Happy to get questions!
I did not see multiquote, but you can build your own quote by hand. For example, I could write, Brownie, you said:
How do you put more than one quote into a reply? I drove myself batty trying to do this earlier, and ended up just posting two separate replies. I know there is something called "multiquote" but I can't figure out how to use it.
I copied and pasted what you said. I selected it, and then I used the WYSIWYG stuff in the reply editor to make it a quote. That's the quote marks! Click it again to UNquote, and go back out to the left margin.
How you insert a link is also the same. You'd use the stuff at the top (or write your own HTML). For example, you'd highlight some words, go up to the top bar, click the chain (not the broken one), and a window will come up asking for the URL and some other info. Remember to put in a FULL url including http:// or https://
