The All-in-One Calendar is one of those plugins that one has to believe was specially developed for event-heavy nonprofits in mind. It easily, and beautifully, allows one to find and share events. Already installed and running on more than 20,000 websites, and translated into 11 languages, the All-in-One Calendar is purportedly one of the most feature-rich calendar systems in the world. We’ve tried it on a couple of our client webs, and we think it’s pretty cool. Go to: http://time.ly to download it for free.
