The sgroup mailing list will be moving very soon (late January, early February 2004) to this site. More details will be forthcoming, and will be put here in due time.
More to come (soon) - in the meantime, see http://www.generalconcepts.com/sgroup/ for all the information.
You may ask, why is this a .ca domain? I thought it would be simplest to name it "sgroup.something" and all the .net .org .com variants were taken, and I don't like those new-fangled top-level domains (.info, .biz and the like). I live in Canada, and sgroup.ca was available and simple (and cheap) to get and maintain.
Don't get fooled by the .ca -- the sgroup has always been, and will of course remain, an international group, with members from all over.
