Apologies to everyone that received a spam message from my richard.arblaster gmail account, it seems that my account had been infiltrated by a spam/phishing bot.
The password was changed last night.
Do not under any circumstances click the link contained within that email, just delete it.
As a precaution change your gmail password.
Rest assured that email was definitely NOT sent by me, I hate both types of spam the email/snail mail/leaflet and the real life meat variety.
