When on the brainstorming page; it only shows You're not allowed to create topics in this category and does not appear as an option when creating a new topic. There seems to be no clear UI feedback relating to this.
I’ve tried to search all around to find the reason, but to no avail.
Could someone explain what requirements are needed to post in Brainstorming?
EDIT: For anyone else running into this; I had to increase trust level through actions & exploring the site.
Not sure at all… .but i suspect you first have to level up like in a game.
Would be nice if there was something noted in UI, but I guess it’s about participating more in the community first?
Do you know if there’s anywhere that shows what trust level you currently have or anything like that? >> looking @ badges etc now 
Click on your profile and then select badges and you should see it in there. You’ve got the basic badge which should give you access to all essential community functions, whatever that means
Seems all good now, just got in and made my first post over there - thanks everyone
