I do have a secondary account, User:Tazerthedog, that I use for testing purposes. I may also use it if I'm editing from a non-secure location.
"If you're ever unhappy about something I've done, or haven't done, or how, or why - please tell me directly. Let me be the first to know; not the second, not the third, not the last. If you tell me right away, maybe I can fix things before they get too bad." from WP:BELLY
The more userboxes you have, the less each one means.
