i found the server operator mod that comes with FLMM does the changes you are looking for
just run that and you should be set
you can also open the mod and see hoe the changes are made, which is a good idea if you use any anti-cheat programs because, some ships start with a loadout that has them with weapons they normally can't equip since they are too high a class
that in effect coula cause players to be kicked or banned
had that problem on my server with the anubis for awhile

ok buddy i explained that for you before as for the welcome message get iron cross server operator and set to auto update of your players you get welcome message now look concentrate
