Down the comments section below, post and include what you want, name and level of Pokemon you want, name and level of Pokemon you will offer, and your username.
Reply if you are interested. When doing so, reply saying that you are interested and mention your username as well.
And if you get scammed, do not complain so trade at your own risk.
To trade you need at least the first badge from Brock and be in the Project: Pokemon group/community
