I have researched for a long time and found that the brief system is a bad system. In this system new people are not getting work, new people are not able to show proof by working even after learning work. If one does not work or cannot show proof of work to the sellers then how will he advance? Again those old sellers are taking orders from their rank gigs. Most of them don't need to be briefed but they are being briefed. It is definitely inappropriate. In my opinion the buyer request should be brought back.Then new sellers like me can introduce myself to buyers.
