One of my teammates is out of the game for good (wasn’t playing for 3-5 months now, I think), and I made him a Commander in my clan, so I can’t neither kick him from the clan, nor contact him to ask if he’s ever coming back to the game (if not, I’d ask him to leave the clan).
Any way I can know his SteamID?
Nope, but you can contact support and have him demoted so that you can remove him.
The in game name of a Steam player should be the same as their Steam user name, so you can still try a search through that avenue.
That turns out not to be the case. Wolveroach is most certainly not my Steam user name.
Thanks, did that, and they’ve helped!
