I'm pulling this from past experiences and from discussions I had with other players and with server management, who have the consensus that the focus should be on LSGOV for the time being - which I agree with. Even that "another community" had issues with their government, from inactive Senators to an LSGOV who as far as I know had a problem with activity as well. Not to mention their attempt of fielding both LSGOV and SAGOV was challenged by the server management over there due to its effectiveness. Interest is a tricky thing, we had interest on SAMP as well, but it didn't mean people were interested in roleplaying with the government - they were just supportive of the concept.
I did propose an IC Senate initially but as I said the idea was cast aside for the time being. I don't mind bringing it up again and seeing if it's possible, but we definitely won't have a fully functioning SAGOV for now.
