The unofficial summary is essentially feel free to use the work you see on this site in both commerical and non-commercial uses. I only require that you attribute me (either Rimu Shuang or my actual name) in whatever derivative works my work is used in or in any locations my work is used in. If there are exceptions, they will be noted where the work appears (usually this is in the case of work I get from third parties, which may have a more restrictive license such as a requirement that derivative work be used in a noncommercial context or various copyleft requirements).
