Andrew Martin discovered why my original message below kept bouncing. Thanks Andrew for sharing this info. I am pleased to announce that the Grid Forum Steering Group has approved the charter of the Firewall Issues Research Group. The group now has its own mailing list called fi-rg@ggf.org You are invited to join to this list by sending a message to majordomo@ggf.org with the following line in the TEXT of the message: s*bscribe fi-rg (replace * by u - this was the reason why the message originally kept bouncing) the subject of the email is ignored. As the next GGF is approaching fast, I would like to invite everybody, including the people who agreed to contribute at GGF13, to create a few paragraphs of text, outlining the subjects you think are important to be researched within this group. Please send your input to the fi-rg list and Inder and I will merge this into a draft document. This document can act as a basis for our discussions. We will then announce a telecon in which we can discuss the input received. We are currently setting up gridforge for the fi-rg which will soon contain the charter and minutes and presentations of the GGF13 BOF. Kind regards .. Leon Gommans.
