In the access control in the admin area you have "read" & "write" against the groups, when I click on the read & write options they go grey but do not appear to change my ability to read or write to that particular category, is this purely because I am a admin or am I missing the point?
Hmm I don't think we expose isAdmin and isModerator globally to the templates so that you can them everywhere. Maybe we should, everything in the config object is exposed so if you open your console and type config any variable you see under that object you can use in the templates. You can also take a look at the routes by prepending api to the url like https://community.nodebb.org/api/topic/1917/users-shouldn-t-be-able-to-purge-their-posts/10 you can use stuff from there in the template as well.
