Faction members, invite indies into your group. You invite them in, you set an example for them in group chat, yadda yadda yadda. They'll feel welcomed and more obliged to RP.
For example, there's a difference between being in a group and seeing orders being given, like "Target the gunboat!" or something, and being outside the group and just seeing lawfuls rape the unlawfuls. Or vice versa, as the case may be.
