Feel free to contact me however you want. I check them all and most feed into email or my phone. If it is urgent, please call. If it can wait for me to check email, wonderful. Its usually best to have something documented for reference, etc. I check email often from my iPhone or CPU.
My calendar will give you a heads up to my travel and conference days just in case you are wondering if I am plopped in front of a computer staring out a window or not.
