I'm going to roll out a new domain name, and have various addresses to the left of the "at" for various different purposes.
Suggest an address to put on the business cards for the IT consultancy and computer network engineering business
Suggest an address to use for communications with DNS registrars and SSL certificate authorities
Suggest an address to quote in respectable SFnal publications like Vector, Mostly Harmless and Banana Wings
Suggest an address to quote in dodgy SFnal publications like Convers[at]ions, Fermat and Mongolian Jird
Suggest an address to use when signing up for things on vendor websites with suspicious-looking privacy policies
Suggest an address to put on the website to entrap evil web-crawling spambots
