Its not a problem,  personally,  I'll be a bit more leniant during the weekends,  and I can understand if people don't post all the time.  So,  I'm not mad,  I just don't want the game to slow to a crawl, and have all of my players lose interest.  Heck,  if you know your going to be away,  just send me a message and I'll NPC your character in combat,  but I need advanced warning.
