I loved QWK packets. That saved me a ton of long distance telephone charges. I didn't use OLX ("Silly Little Mail Reader" was my jam) but the concept was wonderful.
Yeah. My primary BBS was relatively nearby in the same state. But in those days intrastate US calls outside of your very local area could actually cost more than interstate.
Ah SLMR is OLX.
Mustang Software (Wildcat! BBS) bought Qmodem and SLMR (and renamed the latter to OLX).
