Re: If I had to register...
Yeah, nice idea that, tagging email addresses. However more often than not I see that web forms either reject the plus sign, or strip anything to right of it, until they hit the @ .
So, this one is working at less and less places.
10minutemail if I need to register for something needed once. Or a whole list of throw away accounts, one per vendor. Yes, PITA, but using something like keypass helps.
