GiGs said: Community Sheets (the ones that dont have "By Roll20" in their name) can be edited by anyone in the community. The submission license is on the wiki, and the github repository I believe, but in essence: these sheets have no owners, and anyone in the community is free to edit them. The repository maintainers will perform some quality checks, and will try to catch problematic changes that damage a sheet, and may roll back significant changes that get through, but the principle is that anyone can step in and maintain or improve a sheet. When making changes to a sheet, think of yourself as a community servant. The community relies on people stepping in and doing this public service. But remember- you aren't making changes just for yourself: you have to account for everyone that is already using the sheet. It's a good thing to improve a sheet, as long as the current users agree its an improvement! The main thing to watch out for: don't make changes that will destroy data (e.g. changing attribute names without some version function to transfer the stats from the old attributes to the new). So be careful with data, think of the users, and you're golden. Thank you for the information, I am working on updating it. Once I'm done I'll test it and then submit it for review.
