Thanks for asking. If they know the Monthly Meeting, WikiTree members should use that and not add the general Irish Quakers category too. This reflects the general WikiTree principle that we use narrower rather than broader categories.
Incidentally, the Quakers Project uses Monthly Meetings for categorising Quakers, not individual local meetings, and is not creating categories for local meetings.
I have removed the Irish Quakers category from James Lindley's profile.
