Validator is now v3.2.1, but it's a transparent upgrade, so it shouldn't affect anything here.
How to change /category/ to /channel/?
Title says it all. How do I accomplish this?
I was thinking about changing the folder name but that would probably mess a lot of things up.
As it currently stands,
categoryis hard coded into NodeBB. It will require a lot of work to make the paths custom, but it is a planned feature. So, you will either have to just not change the path or get somebody to change all of the hard coded areas that need to be notified in the site code.
