Over the past few days I've added some features, in order of descending coolness

1 - you can rate pictures and videos

2 - you can schedule reminders for events (just view the event details and you'll see the little form)

3 - pictures show the EXIF info ... which is only useful if you're a photography nut like me

4 - for pictures, it gives you the bb code for the thumbnail & the larger version so you can pick which one when you post the pictures on other websites
