Before I finish, I want to add. In the source code distribution file, it plainly states:
"When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things."
Technically according to the GNU Pub release, as long as I give credit to the RunUO owner/developers, I can edit and distribute all I want, if I dont sell it for a profit.
