H left this note on my comment box. Fishy.

If this offer were sincere, why won't he/she just use a name instead of an initial? Also, I googled the e-mail address k5sino@bigstring.com. It brought me to around 10 blogs. H has been dropping by a lot of blogs, leaving the same message.

I wonder who else got this uncanny message from H. I wonder who actually e-mailed H.
