Hmm... here's one for LT...
Forum sends out birthday greetings, but doesn't necessarily post them in the forum announcement section for that purpose. Mine isn't announced here, but I do get an email.
How many of our missing members have the message returned as invalid or no longer in service? Does LT keep track? My way of thinking is that when they get the message it might jolt their interest to return, but if it's returned they may no longer be around and that could be a more difinitive answer to threads such as this one... Where is GillesD???
