I clicked on Dumfries & got clubs from all over the UK. Edinburgh apparently has no clubs. Not such a good system - perhaps with time it may improve.
You have to understand how it works. "clicking on dumfries" has no meaning, there is no search facility (as yet). The map zooms in towards the point you have clicked. Keep clicking and it will narrow down the clubs it shows.
The clubs in the list are those in the current view - not near where you have clicked. If there are still too many, click again. Eventually you get down to street level.
What clubs are there depends on what clubs have been entered, so far.
