It looks like the edit was a moderator noting that because the author didn't include a license with ISA MapSat, it was released in an "all rights reserved" situation. IE, we can't take the existing mod and update it without violating the original author's rights. Hopefully Innsewerants will come back and either clarify the license, or start working again on the mod. (I really hope for the latter, I love seeing someone blossom and learn from these things)
