There clearly aren't that many countries that you've not yet been chucked out of, DTC ;-)
>>> Most ABers seem to be UK
That's probably because AB has its HQ in that great cosmopolitan metropolis known as Kettering ;-)
I'm in the UK (in the bit known as 'Saarfuk' to the locals).
I'm not sure who's overseas these days. Sqad was in the Balearic Isles but I've got a feeling that he might have returned to the UK. (Blackpool, possibly?). Khandro was in Germany but he might have returned here too.
Seekeerz and 1ozzy are both in Australia. (There's at least one other ABer down under too but I can't recall who it is).
Gness and Sunny-Dave are in Ireland, as are quite a few of the crossword puzzlers here, I believe.
JJ109 is in Thailand.
Netibiza is, to the best of my knowledge, actually in Ibiza (unlike Malagabob, whom I believe to be in the UK).
Piggynose is in Spain.
