Depending on your stated gender in the registration form, it may ask you to do any number of actions to prove you're human.
I was wondering if nodeBB can be configured so that topics can be created within groups rather than general categories.
For example, from the "Gamers" group page, can one create a topic such as First Person Shooters or PS4 vs Xbox One or something like that so any topics created in that group are specific to that group rather than specific to a category?
@tdlincoln yes, but not the way you're thinking.
Instead of posting to the group, you'll want to create a new category that only this group has view and posting privileges to.
Then it'll be their forum, in a way.
but why showing other posts from other categories in this group?
