Between Session Communication

This past weekend my Valnwall campaign just finished our seventh session.  At an average of 10.5 hours each, that is 73.5 hours or their lives they will never ever get back!  :)  We have character levels of two (2), three (3), and four (3).

I sent an email to all the players for feed back, critique, constructive criticism, or plain ole gripes (or kudos).  I wanted to give the players a chance to let me know what they thought, and more so, to help me as the LL\DM.  Alas as seems common, I did not get many replies.  I did get a few "having a great time" or "its great keep it up" statements, but I was really hoping for more "constructive criticism" type remarks.  What would make the game more fun or interesting?  "You always seem to pick me when there is a random happening."  "You stink at funny voices."  "The world needs more spidergoats."  Some things like that would be nice as well.

It does appear that when trying to communicate between sessions via email that some people are almost allergic to it.  Seems strange that most of us use it every day in our work and personal lives.  Sometimes too much.  Perhaps that is a reason for NOT using it in between face to face sessions, separation of work and hobby life.

I suppose I will soldier on, and hope there is not a player mutiny brewing in the shadows.  :)
