If you’d like to contact me about anything on my blog, your best bet is to just post a comment. But if you’d rather email me, firstname.lastname@example.org is the address to use.
I used to put a contact form up here, but maintaining a supported plugin across WordPress upgrades was too much of a hassle so I stopped. If you don’t have an email account with easy web access (and browser integration for
mailto: links like the one above), I recommend GMail.
