I have a lot of experience in participating in many projects, including being a Tao Voter. With this experience and great love for Tokensoft, I propose to release special nfts (can be in the form of POAP, to save money). For example, it had functions like privilege:
increased coefficient to get to the top of the queue when participating in token purchases;
a coefficient increasing the right to vote in the Dao, so that it is not the rich who influence the project, but the first, most loyal users;
increased APYs in staking on certain sites, this can be implemented like this, i.e. creating colaborations;
the list can be supplemented with community suggestions.
I fully support that the history of interaction in the DAO, affect the characteristics of karma (for example) and from it give different priorities in the IDO and various events in the life of the community. I was only suggesting to do it as a NFT passport with SNS name
