So I've been creating a customized setup for the AutoIt scripting language, now I can't find any user license agreement or Terms of Use guidelines, I just wanted to know if I could post it on a forum I frequent a lot and maybe change the text editors icon if that's ok, not removing any credits or anything else, just the icon.
Where can I get info on sharing restrictions etc?

Edit: This is for the HiEditor of course, if it wasn't obvious.
