Yup I said "If I remember well" or something along those lines. I'm my mod I made diplomats recruitable and somewhat diplomacy is more flexible. I'll upload it when I have the time. =o)
EDIT: I have seen the description and is right there, you can now recruit diplomats. However I think I didn't touched the relations status a lot, and the script that forces the empire alliances is still there so is not a free for all diplomacy thing.
