The site will flag posts from new members for moderator review based on the algorithms the site owners have set. That message means the post is in a queue for a (volunteer) moderator to review and release when they log in and perform those functions. There isnt any additional notification you need to make, nor anything you need to do but wait.
Basically, you need to wait for a volunteer to review and release the post. Moderation here is broken up in various roles, due to the size of the site. An example of this is, I myself have no access to moderate anything in the model S or X subforums, so if that is where you posted, your post will not appear in my mod queue for action, nor will I be able to release it for you.
Anyway, it may not be what you want to hear, but the answer is, you will need to wait for a mod to log in and check their queues, and the moderators here are volunteers (its not a paid role) so thats as an individual mods time permits.
