Have looked on FAQ but for some reason the colours on it just don't compute with my PC - it is all brown with grey writing and I can't read it all. It could be just my PC - when people send us photos they are always very dark.
Hmmm - it should be grey writing on blue (from a blue background graphic and a transparent shaded forefround). Could you let me know what system and background you're using? (and maybe try viewing the FAQ with a different browser to see if it looks the same)
Anyway - the rules (in the box) do not clearly say the answer - it is clear that if your tile has say two "end caps" (not sure what others terms them but you should get the idea) on it that contribute to the same city , then you only get credit for the tile once.
For the example given though, we play it that if a tile completes two separate cities then you get the credit for the tile in each city. In the games we play it is actually more common to have this type of scenario with roads (ie complete two roads with the one tile) - again in this case we count the tile as contributing to both roads.
That's basicially it. A tile with two segments in one city counts only once - but if the two segments are in two cities, they count separately.
I presume that with this type of question you are trying to get people to use the FAQ etc so maybe just send me a message or whatever to let me know whether I'm right or wrong - or post a reply - might create an interesting debate though expecially if others do it differently.
I think that was Gantry's idea! He'll have to give us the reference he was thinking of, though
