There's several of them on the Daily Telegraph page/
I liked this one
"
If you want to have multiple versions of your email addess, you can just add in a full stop to your email address. Google will send the same emails to
[email protected] to
[email protected].
If Sam wanted even more aliases, he could be
[email protected] or any other variation.
Handy tip if you want to use multiple email alises to sign up to different web services or newsletters."
