Your email address is optional, but if you don't include it I can't get back to you. Occasionally I post email to the site, please let me know if your email is of a private nature. You can enter up to two URLs, any more and it gets round-filed before any human sees it. This eliminates 90% of my spam, and thus makes me happy. I also auto-round-file anything that says "cool," "site," "visit," or "tripod." Spammers love telling me how cool my site is.
