The meetings run from Friday afternoon to early Saturday evening under the Chatham House Rule and aim to provide a convivial environment for a small group of interested members to address an issue in depth.

Attendance at SIGs is limited to members and the occasional invited expert with places (usually no more than 20) allocated on a first come first served basis. Members pay their own accommodation and subsistence costs but otherwise attendance is free.

The outputs of SIGs are generally published through this website.
