Life happens of course but please let us know if possible here if you're going to be away for a while. A quick post to let us know you'll be gone here, so we know what's going on on your end. You don't need to go into detail but if you going away from a couple of days notice prior would be nice.
This is different then a suggetion for the site. If you find something you like about the site or are having problems navagating something/understanding something this is where to let us know.
