Well the alternative is to use the new chat feature and try to talk to people on the strike playlists. I met quite a few people that way and it's because of that I was able to screen who I was adding. If we jived, I'd just ask "Hey man mind if I add you? I'm trying to get enough good people together to run the raid." Throw in a comment with a built in compliment and there's no reason they should say no. If you're already running strikes, you're half way there. You don't have to build lifelong relationships and invite each other over for Christmas. I know this isn't the answer you wanted, but I did it out of necessity and managed to get a few groups together. I even got invites to raid from some of those people because they knew other people, too. It's networking. Good luck man. (I'm 33 with 2 kids. I get the pain, totally.)
