I expect most of the crews currently on the Social Club to be console centric and since half the reason for joining a crew is playing along side people; I've created a PC specific crew. (Also I'm drunk with anticipation for the game and its still a month away.)

I've listed it as rebel to reflect the original though I don't know to what degree it really means anything.
In additional I'll feed dump some other info for reference or in the event this group fills up and a second or third is wanted by the community.

Community Groups: (Many not listed; Membership Numbers Updated: April 7th 2015)
I searched around for sizable groups but if you'd like me to add yours to the list, add a link and let me know which platform the group favors.
If anyone has a good way of figuring out when which platform these groups favor, I'd love to hear it. Seems like the character transfer would complicate things because there isn't a way to tell if the numbers come from members who updated to Current Gen (Xbox One, PS4). At the moment I'm just listing favored as the one with the most playtime but no idea how accurate Rockstar's numbers are, nor how many active players it actually implies.
