Here are few use cases for the GIL Token:
1- Governance - Voting - Token Holders can use the Token to vote on proposals, features, token economy, etc. which will create a fair, democratic platform powered by the community.
2- Increase quality content and organic growth: by incentivizing productive contribution to the platform such as writing Good reviews, flagging inappropriate activities, social engagement - Gilgamesh user base will grow organically with Love & Passion.
3- Use GIL token to purchase Books, eBooks, Audio Books - Authors can purchase services from service providers such as (Book cover design, copy editors, ...)
4- Advertisements - Authors and Service providers can place Ads on the Gilgamesh Platform to target their designed book community members.

So what should be the use case of this coin?
I've read your WP and generally understood the aiming. In my opinion, WP lacks particular examples of usage hence suggest to put some cases.
