Please use the following format for thread titles-

Letterbox, Stoke on Trent, Staffordshire

Please note that a comma after the subject looks neater than a dash and that dashes are not required on hyphenated names (and in actual fact can screw up URLs)

For multiple examples of something from the same location it is not necessary to number them in the title as this is what the similar threads feature underneath the threads is for, just list separately using the same title
