There are two: rsgb_lf_group at blacksheep.org (the old Majordomo-based system) and rsgb_lf_group at yahoogroups.co.uk (the new one). I found the total traffic for the two was too much, so I unsubscribed from the old system and concentrated on the new one. The Yahoo group may perhaps have a digest mode (they often do) but I have not investigated.. John F5VLF
