You might look at my calendar and compare it to yours. When you have a couple of dates that might work, contact me.
My cell phone occasionally loses messages when I am on the road, so call back if I don't return your call. Similarly I have an overly aggressive SPAM filter that occasionally tosses good email. In short, if I don't get back with you, please try again. The likelihood is there was a technical glitch and I never got your message.
