A few days ago, I received an e-mail from a loyal floss reader in the San Francisco area asking for some advice. Whoever you are, I accidentally deleted that e-mail, and apologize. If you happen to see this mini-post, please don't hesitate to write again. Here at the _floss, we pride ourselves on returning all our readers' e-mails... unless the subject line suggests we regenerate our manhood, or some such thing.
