I haven't yet. I should have it installed for testing early next week.
I have a url I picked up unrelated to my vB sites that I'm going to try it out on. It used to be a blog about Disney World and still has quite a few links coming in. I figured it would be a good place to test out pligg before trying a larger implementation. That url is
www.disneybuzz.com. It's parked with trafficz right now.
