In cases we get products from different sources before the GBs are started, we usually share them (on FUB) for everyone for free without any restrictions.
These products need not to be GBs on other forums, and they must be appropriate content and share the same types of topics allowed in FUB.
If they do, please feel free to share the link to the source of the product (even if they are outside GI) or share them on FUB and link to your topic in FUB.
