Hi. You know you can add multiple categories to a page at the same time, right? You don’t have to add them one at a time as you have been doing. It could save you some time if you just add all of the categories you want for a page all at once. :)
Hmm, I wonder if there’s something weird going on with your wiki’s code that’s making the pages freeze. I obviously haven’t tried adding categories here yet, but I am curious if the page freezes affect everyone or not.
I’m just curious. I didn’t see any others listed on your profile page, so I didnt know if you just spent all your time here or not. I have a couple others where I’m admin and spend a lot of my time: one that’s pretty old and there’s really just two of us who edit, and one that I started and am still trying to get on its feet.
Check out your Admin Dashboard, which can be found by clicking "Admin" on the bottom toolbar -- it has links to all your new tools. Please let me know if you have any questions, and good luck with your new (old) wiki!
