RSS Advisory Board now has a wiki provided by member Ross Mayfield and Socialtext.
The impetus behind the launch of the workspace is to support efforts on the RSS-Public mailing list, such as software tests like one that I've been conducting to see how well aggregators can display a diaresis character.
(Loïc Le Meur has agreed to be a diacritical test subject.)
Anyone can create an account and edit pages, as long as the content's related in some form to what we're doing on the advisory board. The wiki can be used to collectively draft etiquette policies and other guidelines as they become necessary. Feel free to experiment with its collaboration tools.
