I sent messages to the first three names on the Master list hoping to get an invite to the clan so friending the active guys would be easier, If there is a better way I am open to suggestions. I dont play online a whole lot and it looks like there is no way to see who is active and whose not.

Hey, I'm BarelyEvolved I'm mostly A dirty casual playing PS4 games when I get the chance, I'm currently playing Warframe looking to get into a clan and It sounds Like this would be a good fit for me.
