Well in order to post in the promote yourself section you need to be a full member of the forums which means either : -
a) You have a total of 30 forum messages (these are interactions you have across the forum threads / replies to threads you want to participate on)
OR
b) You have partnered with the Freedom Network (or our sub network the MGN) and then request the partner badge, which is usually updated to your account within 24-48 hours.
Hope that clears things up, if you have other questions please don't hesitate to get in touch
