Here is how you can resend your confirmation e-mail:
1. Go to www.tomshardware.com and click log out in the upper right, if you are logged in currently.
2. In the upper right click Sign In.
3. A window will pop up. In that window, click the link that says "You did not receive the confirmation email?"
4. Input your e-mail address, and the confirmation e-mail should be resent.
If this still does not work, please try creating your account with an alternative e-mail. Please bear in mind that some email providers may flag account confirmation emails as spam, so be certain to check in your spam folder for the email.
Hope this helps!
