Especially if we're halfway through a game! If you do want to join, send me a message and I'm generally happy to invite you in, but please don't just join when we're partway through a game! We might be playing with certain weapons or having a showdown and if you join halfway through without knowing what we're doing it could upset the balance. I know you can set your fire team to invite only, but occasionally I forget. I've also had it a couple of times where I was disconnected from the game and the fireteam settings returned to default. It's just common courtesy to ask! Tl;dr Don't just join, ask first. Edit: Given everyone keeps mentioning it, I [i]have[/i] sent this to people on my friends list. Those that keep doing it on my friends list will be removed. Just wanted to send out a little reminder of common courtesy to everyone else, even if it doesn't apply to most people as they don't join without asking
