I got my start with BBSes, lots of fond memories. There was one BBS in my area, and they had it setup to RelayNet (similar to FidoNet, but smaller). I knew when they would connect up to exchange, so I would be sure to upload my mail packet and then dial back up 5 minutes after they did their exchange to see if I had any new messages. I could send and reply to messages across the country in a matter of days.
