Without wanting to incur the wrath of the almighty (sorry Danny), it is worth making th epoint that I tried to make earlier
Any publically available page on the web that contains an e-mail address is open to having that address harvested by automated spiders, and the e-mail address added to spam lists.
There are actually people who make money out of selling e-mail addresses they have garnered in this way, adn of course the addresses become more valuable if they can be linked to certain attributes - eg flying, or a love of it.
The moral is don't publish your e-mail address anywhere on the web if you don't want spam, and also don't forward interesting jokes or pictures with long lists of mail addresses on them.
