We don’t do mobiles and there isn’t enough happening here to bring me to this site more than a couple of times a week. “Instant” messaging maybe a bit of a stretch.
So far all but one of our messages have been impersonal, one cut and paste from his profile description. It’s the “off” season for the Wet Tropics so we have been politely responding with links to the blog/questionnaire. It would be nice if we could have an autoreply option for bulk emailers (like helpx does). I don’t think we’ll have the time to school spammers this winter, an autoreply option would be a plus for everybody.
