I'm forwarding an e-mail I got through the Wikibooks e-mail service. As I very rarely get spam this way (I think this is the first genuine one), I think it does deserve some note and I'm letting others on this mailing list to make sure you don't make the mistake of actually trying to make the massive links to this guy's website. I don't think that is a serious problem with regular Wikibookians, but a mass reply to this guy to let him know he has stepped over the line may be appropriate.
I also mention this to Wikibooks admins that there may be some attempts at link spamming by this indivdual and others, depending on how far this individual has gone through the Wikibooks user list.
