Hey DaCor,

Try to describe changes, please. I.e.
'Corrected tagging for pharmacy'
tells other mappers more than 'fix'.

Also, I would recommend checking your changes with the official website for each POI and discussing it with other mappers -at least where you are not sure- (as the change is not just fixing an obvious typo; these two tags should not be confused with each other). If possible, submit improvements to NSI for larger brands (open an issue ticket)
https://github.com/osmlab/name-suggestion-index
(such as Superdrug)
and additional terms/translations to iD so a tag is more easily found

(See 'Translate!' link for translations)

Regards,

Daniel
