Well...I've been involved in a number of OpenACS sites. www.royal.com is the biggest, but by no means the best implementation of OpenACS technology. www.edulix.com is a little more community oriented. My main project right now is
http://www.vwbusclub.com/ which will eventually make use of most of the ACS. Currently we are using pdm, chunks, faq, news, calendar, glossary, general-links, general-comments, classifieds, ecommerce (not fully implemented yet), neighbor to neighbor, polls, whoisonline and my pet project...a HEAVILY modified forums.
I am currently building three other full ecommerce sites with it as well. Fun fun fun.
