Can't post in market place

Hi I can't seem to post in the market place as I'm wanting to do trade on my blackberry dtek 50. It says my account has not got permission to post in the market thread.

Please note that offering a device for sale can only be done within the CrackBerry Marketplace, after meeting time and posting criteria. You can read the details here: https://forums.crackberry.com/market...lines-1105833/

Please do not post offers to sell in other threads.

Thanks for understanding.
