Don't respond to every message. A general rule is to pick one or two topics of interest or expertise and stay with those for a while. Restrain your ego. AR-talk isn't about proving your point or defending your views as much as it is about publishing accurate information on resource availability. If, after having subscribed for awhile, you find that you don't care for the sort of discussions you find on the AR-talk, please unsubscribe quietly.
Truth has no fear of investigation.
If this list rubs you the wrong way, let's just agree to disagree and part on amicable terms. If you have more than one Internet address, make sure that when you post messages to AR-talk you do so using the address from which you receive your messages. On some host systems, if you don't check your mail often enough your mailbox fills up. When that happens the host rejects incoming messages to your account. As a result, then OUR mailbox begins to swamp.
