This is a fantastic idea and needs looking into by someone! I'm in UK and i'm sure there are so many more people who will agree with this but haven't heard of this site.
i love this show, and i agree with a spin-off, i have had the same ideas running thru my head ever since the announcement of the cancellation of the show, if alyssa milano and rose acgowan have agreed to make a ninth season, why dont they, i mean im sure holly marie combs wouldnt mind either, so i think that the new WB company should seriously think about either continuing the original charmed or do the spin-off, i would like to see the original kept going myself, but i am only one person, but the amount of fans i have heard about, it would be stupid to cancel the show all together, anyway, i love this show, so plz keep something going with it.
