forum issues

Hi, I'm posting here as I don't know where else to ask: why can't I post in Advertising, Marketing, Social Media? Screen shot below. Only the "attach files" button works, the rest do nothing.

I really need to get in touch with anyone who has successfully run a forum website and is willing to teach me everything I need to know and guide me to becoming equally successful in the same area as I am preparing to create one. Thank You.

Hey everyone, I’m excited to join the fast lane forum community. Furthermore, since I am looking to get in to the app business very soon I was wondering if there was any forums besides here where appreneurs connect and learn from each other? If so, I would love to know. Thank you Bile.
