I believe the SWAG mail list is still going, although very inactive. I did send a message a few years ago and had a response from someone in Weston Super Mud.
zerohour1974: Well, I'm happy to hear there's at least two of us in Swindon. I'd suggest we plan a beer sometime and call that the first of many SWAG revival meetings.
roberthazelby: Just realised the last posts to the SWAG list were actually me replying to a post of yours ... in 2010
