Hi all, As you're no doubt aware, RIPE 61 will be happening in Rome during the week of November 15th. http://www.ripe.net/ripe/meetings/ripe-61/ The routing working group is tentatively scheduled to meet after lunch on Wednesday, parallel to the Co-operation working group, but bear in mind the agenda is always subject to change. If there is something you'd like to talk about at the meeting, please send Joao and myself a note. Best regards, Rob
