On most skool communities, it is seen as bad form to promote your skool. I found an interesting skool called Skool Classified, which encourages you to post about your skool once a day for free.
I just joined, so don’t know all the ins and outs, but you can post once a day, and don’t DM the other members. There’s also a paid tier (of course) but I dont know what that is about.
Anyway, thought it would be a valuable resource for other skool owners in Barcelona out there!
