Since you have account on the site, you are more than welcome to submit. It's always nice to have guest work on here. I am of the belief that cooperation, rather than competition yields better results.
Typically, Kuro-RPG offers sets as zips and it would be up to the user(s) to decide how they wish to use them. The more information you can provide in the submission, the better. You can also look at existing submissions for ideas on how to present a zip.
