Thanks for the credit, Ronski, but all I've done is walk around Margate checking cabinets. You've done all the map creation/updating work plus a lot more background work that I can't imagine.
Anyway, some people seem to be under the illusion that the Margate and Thanet exchanges are different. That's not true. For some reason, the Margate exchange is called Thanet! Perhaps someone knows the history and can enlighten us all. The physical Thanet area includes Margate, Broadstairs and Ramsgate, but only Margate has a different exchange name.
Looking forward to a speed increase!
