Some people also made a similar suggestion via PM, and while I appreciate the thought, I have said it before and I will say it again: I do not and will not under any circumstances make profit from a derivative work of ED and its 3rd Parties and Partners, as dictated by the EULA.
I am not that versed in legal matters, but I do not wish to risk jeopardizing the good relationship I have with them.
These guides have always been free, and will always remain so.
