To go along with my 4 page internet introductory course in a thread below, here's a little tip about avoiding duplicate posts.

When you click the post message button, your message is sent to Greg's board, and then you start waiting for the confirmation response. If you click STOP, it's TOO LATE! The message has already been sent. If you don't receive the confirmation, it doesn't change a thing.

If you're not sure whether it posted, here's a tip. Put a password on the second post. Then when you see it's a duplicate you can delete it.
