Im unsure, there could be a search function in the "find platoon" tab, but you could always add us on your friends list too. doubleg is the general and catman and me and some others is "commissioners".
I ended up buying the base game because I'm poor and only added $50 to my wallet lol Do I need to have someone in the platoon added to join? I believe the account that I use for every other game that isn't GTA doesn't have anyone here that plays BF1 added unless Audi or Zolan are in it.
He is 18 now, and cant recall the exact moment he rejoined, but he made a post in our thread, and I double checked SC, he is a member in our crew.
I don't recall Leaky rejoining after the whole shebang with the "under 18" stuff
