Hi Splodge
I've also had this and an earlier one from the same people.
If you look at all the email addresses it has been sent to it looks as though they may have got the email addresses from TalkBB. At first I thought they had raided our email addy's as a lot of our members names were on the list, but then I realised that there are a few people on the list who post on TalkBB and not on TiBB.
These sort of spams are very annoying and also quite difficult to ban because of the Hotmail.com address.
