I have been a part of this board almost as long as you have. Most of my posts are actual contributions to this forum and its agents. I am not here to solicit. If someone comes along asking for help, I don't see anything wrong with offering them help.
How long anyone has been on this board I think is irrelevant.
You are soliciting! For money! If your referrals were given unselfishly without expecting compensation, I would understand.
Referral fees cost buyers and sellers money and should be disclosed up front to them.
As I mentioned, there also is a specific section for referrals.
