Collecting Wedding (or any event) Photos with Flikr!

I have been trying to figure out a good way to collect guest shots....thought about leaving a box of blank disks with pre-addressed envelopes, then realized people are slackers about getting photos off their cameras onto disks.  This might solve my problem as long as I include clear directions and maybe even my e-mail address in case guests have questions.  Flickr has a fantastic set of tools available for the DIY wedding album builder.  You can create a group and then invite your guests to join the group and post pictures from your event.  You then have access to all their pictures to enhance the collection you're slowing starting to amass.
