My email is always open (email me at firstname.lastname@example.org) though please understand that I work a full time job as well as a part time one, and it takes me days (sometimes weeks) to respond properly. (Though, if it’s going to take a long time, I generally fire off a ‘hey, I got this and I plan on responding at such and when’ non-email). Or you can use this nifty form, if you’d rather not email.
Please note: anything rude, mean, or tearing-down-y will be displayed publicly. Consider that when hitting the send button. (Generally this is a non-issue, but you know. Just in case.)
