Are you a developer? If your intention is to personally help add the variant to the server, then you would likely need to contact @BabYagun or @qilp for specifics. Otherwise, I'm not sure what you mean by using https://www.chess.com/clubs/forum/view/requirements-for-submission since that refers to submitting custom variants on Variants World, not completely new variants requiring new gamerules.
Volunteer to add variant Musketeer Chess
Maybe a Musketeer Chess like variant on Chess.com,but with already existing chess.com fairy pieces and a few rules rid of regular musketeer chess?.Maybe that kind of variant should be called "Arquebues Chess" or another simpler name.

Yes, I'm a developer and that's my intention. I have experience creating chess websites and chess apps, both standard chess and variants.

@BabYagun @qilp Would you please give instructions?
About Musketeer Chess variant:
https://musketeerchess.net/p/games/musketeer/rules/rules-short.php
I'd like to volunteer to add the variant to chess.com website. Is there an instruction how to proceed?
As I understand, the default way to add a new variant is to create the rules for the new variant, using this tool:
https://www.chess.com/variants/custom
Then post an announcement about it, following this guide:
https://www.chess.com/clubs/forum/view/requirements-for-submission
Then we'll submit the variant (with the created rules) by posting an announcement, following this guide:
https://www.chess.com/clubs/forum/view/requirements-for-submission
But Musketeer Chess requires custom UI and rules that the tool above doesn't support.
How to proceed in this case?
