I'm so sorry - I just did a partial view source on one of the links and see what the problem is....when I copy and paste Free's text, I always get a little black square for quotation marks - usually I never change it in my text, because it displays as quotation marks (or a dash - a dash that Free types also copies and pastes as a little black square - but it displays the way it's supposed to)
When I viewed partial source just now, I see that there are DOUBLE quotation marks around the url addy, which voids the link entirely. This is very upsetting - all those links are worthless now, unless one wants to do the same thing I did - view partial source, take out one set of quotation marks, and then paste the url in your browser. : (
