2 prong

Many services/tools on the internet require email confirmation to sign up, and leaving one's email all over the net can of course generate a lot of annoying spam. One solution is to have a separate email account for sign-ups, but another nifty solution comes from 2 prong When you visit the 2prong page, a disposable email address is automatically copied to your clipboard. Paste(ctrl V)that email address into any email confirmation form, and a few minutes later the email will pop up in a box in the "2prong" window. Then just click on the confirmation url you've been sent, and you're all signed up.
