Please Google the Sherman Anti Trust act. I for one would welcome a discussion, but Federal law prohibits agents from doing anything that appears to indicate there is a standard or normal pricing. As I understand things, you are allowed to say, Hire Me, I charge X% for my service, but the minute two agents from different offices discuss commission amounts, it's considered a conspiracy to fix pricing.
I don't know if anyone will take you down, but rather than risk it, I'd encourage this post and the other to be removed. How you decide to proceed is up to you, but you can also ask your broker since if I'm correct, they will also be hurt by this.
