I’d like to turn off email notifications for new topics in each category. So I went to my preferences, but it seems like I can’t click on the “×” next to the list of categories I’m watching (or rather I can, but it doesn’t remove anything):
This is now resolved as of the forum upgrade on May 26, 2021. You should now be able to remove categories with the X in your user preferences.

I may have found a workaround for this. If you go to the category list and then choose one of the categories you are watching, I think you can remove it from the “Watching First Post” list there.
