Hi all,
I just started a group on Flickr called "Wikimedia Commons". I encourage anyone who has a Flickr account to join it.
http://www.flickr.com/groups/wikimedia_commons/
It can be used as a way to increase our presence on Flickr and explain the utility of CC-BY and CC-BY-SA licenses to Flickr users, on their own turf where they are much more likely to be receptive to helping us out. Flickr users who are unexperienced with wikis/Commons can post photos to the group where I am sure one of us will gladly transfer them, if they are useful. Flickr users can have the satisfaction of seeing their work in prime web real estate, especially if they photograph famous people for example. :) People who photograph plants can also post photos there to get them IDed before transfer to Commons.
I think some people also post comments on photos when they transfer them to Commons. It might be useful in such a comment to also post a link to this group now, to encourage them to learn more about how they can contribute to Wikimedia, the world's largest and most accessible of open content.
So anyway, all members and discussion now welcome :)
cheers, Brianna user:pfctdayelise
