Well, as a matter of personal policy, I don't want to publish it in any public place. But it is something+something at gmail dot com. (Where "something" is a string of English lowercase letters).
Gmail doesn't let you use "+". How did you manage to pull that off?
As a matter of fact, it lets you. It's a neat advantage of using gmail, which I use to track the origin of spam. Suppose your e-mail is foobar at gmail dot com. You can send mail to any address in the form foobar+something at gmail dot com, and the mail will arrive at the same account, namely foobar at gmail dot com. You can then define filters based on the address used, or you can look at the headers of your spam to see which of the variants was used in the spam.
So, whenever any web site asks me to register, I can give it a unique email address. If I start receiving spam through that unique email address, I know who the #%@@ who sold them my e-mail was.
