Of course, someone could create a category, but you'd still have to put it on the profile, so I recommend you learn the simple process!
First, go to Category: British Columbia to see what naming patterns are already in place. If you can't find it otherwise, go to your "Find" button at the top of the page, and go down the tree -- Category-->Regions-->North America-->Canada-->British Columbia. You'll see that the naming pattern is simple and logical -- town name, followed by British Columbia. You'll also see that there's no current category for your town name.
Second, go to the profile you want to categorize. At the top of the profile, type in [[Category: Spences Bridge, British Columbia]] and save the profile. Leave Edit mode and return to display mode and you'll see it's now there in red. It hasn't been completed yet. Click on the red listing and it will take you to the category page you are creating. Add to that the category that IT is a part of: [[Category: British Columbia]] and save. Since there's already a British Columbia category, it will display in black. And you're done.
Third, go to the other profiles you want to put Spences Bridge on and type in [[Category: Spences Bridge, British Columbia]]. Short cut -- while you're there, right click with your mouse and then click on "Copy". At each succeeding profile, just "paste" that category - and you're done.
Note: Be careful of the spelling. I kept wanting to make it "Spencers" Bridge. If you create the profile wrong, it will live forever, so it will need to go into "Misnamed Categories."
