Right now, e have two ways of creating an idea - either from the profile editing (where you need to know that you have to then go to editing to fill it out) or from the 'roleplay' part (where you need to know to set it to be public.
Recently I had to explain it to two people and none of them saw it as any self-explanatory, and truthfully, I don't find it to be so either, when I think about it. Some sort of simplified option of "create new ad" in roleplay section would be useful - or maybe using the opportunity of what was mentioned in this feedback by WA to make it all more streamlined and easy to know that you need to push specific button/set an option to make an advert.
