Oh, and rab's "500" one was solved above, iirc.

Oh, and Chalky's is DARREN but uses a rather naughty indirect anagram.

[Darren] "Chopped" in this case means beheaded, rather than rearranged. The answer is a fairly uncommon word.

I believe Martha's Doctor was also solved, by CdM if I recall.

And the landmines one was also solved, by MF. And I could have sworn that some one had also posted the answer to Chalky's a while back, but maybe that was my imagination. I know I solved it and then didn't post the answer for some reason. So only the last three of Raak's list are outstanding.
