I’ve set up a Public Flickr Group for Soar Milwaukee to become a repository for photos of our radio control soaring activities Milwaukee area. The Flickr Group is at:
http://www.flickr.com/groups/soarmilwaukee/
If you are already a Flickr member you probably know how to post to group pools but if not, join the group above first then find a photo you uploaded, look at the icons directly above the photo and choose send to group, then pick the group you want to send the photos to. You can do it through the batch tool as well.
If you are not a Flickr member basic memberships are free and Flickr is one of the biggest communities for photo sharing and is a Yahoo! company. Great place.
