Hi folks: well, it looks like iWeb won't allow visitors to leave comments, unless the site is on Mobile.Me. Oh sure, there are several workarounds, but Intensedebate wouldn't let ME see viewer comments on my home computer, and JS-Kit appears to be just a trial version (if I want to keep it, I have to pay some $$ -- not that there's anything wrong with that). I installed UltraGuestbook, but it does move folks to another unrelated website, much like Blogger. However, Blogger LOOKs great and is easy to use.
If any of you have any preferences or tips with regard to having viewer comments posted directly on the Sparkling Apple site, please, well... post a comment right here!
