So, currently I'm OK with being on at 8 tonight, It's easy to set-up a crew only session, the only issue is that the host needs relatively decent interweb speeds. Since its crew only, the crew heirache determine what you can and cant do, so its not an issue if a higher rank isn't host.
In single player, go to On-line in the pause menu, then "Play GTA Online" and select "Closed Crew Session", so only members of your crew can join. If there are crew members already online then send out a crew invite. If you login after its made and dont get auto joined, use the join other crew members function.
I'm happy to host if its not set-up by the time i login should be home 6ish online by about 7 maybe. I think my PSN is ianjb - if not, it will be pyroib
