I have a permissions page now available on this site, detailing permissions for how my work can be distributed and used, etc.
Previously, some of this information (particularly for freeshells and balloons) was available on the index pages, but more and more I've been thinking I wanted to separate it out, both for a cleaner look and so I could detail permissions for other types of works as well.
Alongside this change, the ghost/etc. pages will each link to their respective section on the permissions page, if all has gone well. So if you're unsure of the permissions, it will act as a quick link to the right section for you.
Of course, there may be special permissions for individual works... I haven't decided yet if these will go right on the page for that item, or just be listed in the readme. I'll figure it out once I find some, probably.
Hopefully everything is clear. If anything is unclear, do let me know and I'll be happy to clarify it for you and update the page if needed.
I think as long as you read the introductory section, it will give you a pretty good overview of how I would like my works to be handled in general, and can serve as a guide for understanding the specific details.
