This carries a record of messages since 2001. Fortunately by about 11h00mUT the entire database had been rebuilt using special software supplied by Demon but regrettably a small number of e-mails sent to TAHQ between Apr 16 at about 19h00m and Apr 17 at 11h00mUT may have been lost. Could anyone who sent a message during that period and who has not had a reply please resend? I am sorry for any inconvenience caused.
