I find that an even better one than Hotmail is to get a webmail account with Goth.net. It's free to set up and you're guaranteed at least five or six emails a day promising you a fortune.
There's two posts on the forum at the moment about scammers and reading them is kind of worrying. I only opened an Ebay account myself to buy Amiga stuff and so far have found all the sellers to be really, really good. Efficient and willing to answer idiot questions after I've bought the items. Is scamming really that rife?
