Hi, dotsama community！

This is a follow-up proposal from PolkaWorld to seek to cover the next three months (Dec 2022 to February 2023) of ops and maintenance costs to further promote and support community education for the entail Polkadot ecosystem.

PolkaWorld converted the W3F community grant to an open social contract with Polkadot Treasury in June 2021. Up to now, we have summit 6 [Motions](https://polkadot.polkassembly.io/motion/250), and all works are done in very high quality. You can also learn some of the delivery [here](https://polkadot.polkassembly.io/treasury/160#78ddbc22-acac-4a5f-9883-588928045fce).

Please check all the delivery reports, details for the next 3 months’ milestones, tasks, and the budget [here](https://docs.google.com/document/d/1Z2q3CXSONc01vDFeapAM93C2v8US8gghVKQXnzpDEqw/edit). Love to hear all your advice or any feedback.

Approve a proposal. At a later time, the proposal will be allocated to the beneficiary
and the original deposit will be returned.

May only be called from `T::ApproveOrigin`.
