I know I'm a bit late with this post, but for those of you who haven't already noticed, we have now introduced something called Informal Staff-ups. The idea of the staff-ups are to encourage groups of people to staff up their favourite airports, and we will then advertise them accordingly. This should increase the amount of traffic you'll receive, and make your time on the network more enjoyable. The full details are explained on the forum post here, but we just want to reiterate that these are not formal events, they are simply a way of promoting ATC staffing in the UK and as such, there is no obligation to make an informal staff-up post to be able to control with your friends, nor do informal staffings override any existing CTS bookings. I hope this is (somewhat) clear, and that you all will enjoy this new system!
