Absolutly hit me a PM. I have been a little behind on some emails but more than a day or two is not the norm for us. I use Gmail and from time to time incomeings get filterd and we sometimes in rare cases see that our outgoing don't always get through for some reason. Pm, Skype, twitter, google+ are all alternate options I am good with.
If you don't hear back from me in 24-48 hours one way or another (during the week ) then list me as MIA and send out a search partie for my bodie. The one exception would be the 2-3 time a year I steal a couple work days for a hike.
