1998 August 2, Your RCW 139 - ACAM&AC Organizers, “Due South Convention This Week!”, in tor.arts[1] (Usenet):
It's a whole weekend designed for us to get together with fellow Duesers and celebrate our favorite show.
1999 January 19, Gary L. Dare, “Re: US / CANADA trade dispute (magazines) - BOYCOTT?”, in soc.culture.canada[2] (Usenet):
The bulk of Duesers on alt.tv.due-south are Americans and ask lots of questions about Canada, and express a genuine interest and warmth towards us and our country.
2004 July 14, Adrienne Purple, “Re: Season 2 is on the way!”, in rec.arts.sf.tv.quantum-leap[3] (Usenet):
"Due South" is produced on double-sided CDs and I don't know many Duesers that actually appreciate that, they think it looks cheap apparently.
