I have a cool idea for the calendar. Aside from people being able to add dates to it, the calendar is now a project. It will include a web component and a few pages. Basically, now I'll be able to show, for instance, a small "newspaper" icon on a day that there was news. Of course, I like making these things easily configurable, I'll also be able to have an icon that signifies, say, a new Photo Album added, and on the date the photo album was added, that icon will show up on the calendar. It's going to be neat. Other "calenderable" things I have are downloads and links. This thing is going to be cool.
So also, the calendar control will be clickable and you'll go to a page, when you click a specific date, and it'll show you all the neat things that happened on this site on that date.
