im such a dork I cant even say i forgot, I just didnt do it. sorry man.
I did now though. I made a user group called ‘canberra moderators’ too and made you the owner of it, as you cannot be the owner of a sub category.
Kinda depends what you want to do, if I understand correctly you want a public, open sub cat and just be the moderator of it.
Thats all set up. If you want to add other moderators you should be able to add other users to the group “canberra moderators” as the owner of this group- use the search function 
Heres what the settings for the sub cat look like, theres quite a lot of things that can be tweeked… I’m almost sure as mod you can’t change them, so if there’s anything else just lemme know.
obviously, if anyone in your club wants to generally we are more than happy, its just we only want people who wanna be kinda present.
ah yes and finally, I couldn’t see the logo you uploaded in case you don’t mind trying again
