I know I haven't been in the bubble in almost a year, but what is a "CG"? Thanks.
A CG is a Community Goal, events set up by FD for us wherein we have specific goals to accomplish to 'activate' the CG, which means the first tier of rewards will be payed out, and then further goals which increase the tiers of the rewards.
These events can be to bring cargo to a specific station, like the recent CG that asked for a rare good, Presents, to be delivered to a station a short distance away, under 200LY, and based on the amount of Presents delivered, new players got a new starter ship. That CG reached a high enough tier that new players got a Viper Mk IV.
Here lately they've had 2 CGs going at once, one for cargo and another for bounties, with the bounties being a 'help protect the cargo haulers' bit that allows combat oriented players to also participate in the CG.
