Scallion, you seem to think the two words are supposed to be different in the forum topic:
"Why nix & nix, not *nix & *nux?"
When in reality, a true synonym would be:
"Unix/Linux, and Unix/Linux Security" (yes maybe Gizmo should've put a comma in there so you wouldn't get confused)
Seeing it that way, it makes sense that this forum is for discussion anything-related Unix or Linux. Before it was just Unix/Linux Security and people may have thought that any Unix/Linux discussion in this forum MUST be on security.
So as you can see:
"*nix & *nux Security"
does not work in the meaning Gizmo was trying to get across.
