Unsubscribing

I wonder if you can help me unsubscribe my late husband, Dave Guthrie, from the Ripe mailing list. Dave died in March of this year, and in May I sold our shares of Technocom plc to the Easynet Group. Dave's e-mail address was dave@technocom.co.uk. Since his death, incoming messages have been routed to me at ruth@technocom.co.uk (until the sale of Technocom) and at the.guthries@worldnet.att.net (since May). There have also been occasional uses of @technocom.com and @technocom.net, just to confuse the issue further. If you are able to unsubscribe him, I would appreciate it. If not, have you any advice about how I would do so? Many thanks for your help... Ruth Guthrie
