Oh wow, that's excellent. I never saw, before, how to *link* to a category. I'll go through my new categories and change the links from free spaces to categories.
I really like the Colony of British Columbia category, except I personally think a lot of that information should be on the free space profile, not a category page. I'd prefer not to see more than a couple of sentences (basically location, and start and end dates) on a historical place category. But that's just me, and if everyone decides to do something different, of course that's fine.
You're right about the progression from Newfoundland Colony, to Dominion of Newfoundland, to Newfoundland, to Newfoundland and Labrador... I hadn't realised it was only Newfoundland and Labrador after 2001. I've been sticking 'Newfoundland and Labrador' on all my post-1949 profiles. Now I'm going to have to go back and change them.
I'll make the Dominion of Labrador, and Newfoundland (Canada) categories and free space pages myself. Or, if you want to go ahead---please do. I'm working on Nova Scotia right now.
