An online calendar, that is private/public…RSS feeds for the latest entries.
Implement it on your blog, just like RSS calendar.
From the website:
“Planzo is also one of the Internet’s first social calendar sites, allowing friends to stay connected through its network of users. Add users to your Favorites list to begin sharing events with them and easily surf to their calendar. Leave comments on your friends’ events and mark up their personal wall.”
“Figure out when to plan events. You can see what your friends are up to on one calendar
Share photos, files, bookmarks and text snippets with our Notebook feature
Make a To-Do list for yourself with our To-Do list feature”
Have a go on the demo calendar.
