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.

- There is a proposal called motion 383 for costs from March to August 2023.
- The original amount requested was 16,655 DOT.
- This amount was approved, but there was a mistake in the application.

- They appreciate everyone's understanding and support.
