You'll need to run it past your
GA. Some GAs will be offended if they see you're obtaining other contracts...especially if they offer those carriers. They could:
1) Cut you off from all support
2) Lower your commission
3) Put you as-earned if you signed up for advances
If you don't have an upfront release you're in trouble. If you're obtaining contracts the
GA doesn't even offer you "should" be fine but again, if your
GA thinks you're out writing for other carriers off of his training you could be cut off.
