As far as I understand, there is a limit of number of posts at a time per week. If you have already posted articles up-to the limit for the week, then you have to wait for the week to be over. If you violate the guidelines you will get warning. If your post submitted is pending but you have not crossed the limit of number of articles, you may be able to post. Any way when you post an article, you will get the reason for not allowing your posting if not allowed.
