egoman - Contact Joe Black at .. joe (at) antiquecaterpillar.org .. (insert the @ sign in the appropriate place) and he will be able to sort out your problem. The registration process is screwed down pretty tight to prevent spammers and scammers getting through, and Joe has his work cut out, trying to pick the sleazebags that slip through.
