This is a supplementary proposal for [motion 383](https://polkadot.polkassembly.io/motion/383).
In motion 383, we applied for a 2023/3-2023/8 operational cost of 16655 DOT, which was approved at the time. The details of the proposal can be found [here](https://docs.google.com/document/d/1oJjtkZD8mgv5vRpBh_aoGmWqWlLK9tomGhP8M9esMng/edit?usp=sharing). However, when we filled in the amount of application on chain, we mistakenly wrote 500 DOT instead of 16655 DOT. Therefore, we are applying again for the remaining 16155 DOT, and we hope that the rest of the amount can be voted through as soon as possible. We appreciate your understanding and support.

- Motion 383 requested 16,655 DOT for operational costs from March to August 2023.
- The request was approved, but 500 DOT was mistakenly applied on-chain instead of 16,655 DOT.
- This supplementary proposal seeks approval for the remaining 16,155 DOT.
- The original proposal details are available [here](https://docs.google.com/document/d/1oJjtkZD8mgv5vRpBh_aoGmWqWlLK9tomGhP8M9esMng/edit?usp=sharing).
- The team hopes for a quick vote on the remaining amount.
- They appreciate understanding and support from the community.
