So, for all you Sci-Fi fans out there, what the heck happened to Amanda Tapping and McGyver? Why aren't they on SG-1 any more?

UPDATE: The Paris Metro had a little fire today - I was actually on the same line as it happened, but I was in the southern part of the city, this was in the north. Man, there were TONS of military with machine guns at the Louvre today. Groups of like 8 of them together, and lots of groups. Clearly they're on alert.
