I'm speaking up here, because I directed the original poster to this list via OTRS in the first place. I already gave him tips on Wikipedia participation via OTRS and told him how to contact Cary in order to do direct WMF volunteer work. I directed him here for information on volunteering in the UK / with Wikimedia UK, especially since as far as I know, Wikimedia UK does not yet have many volunteers in Scotland and perhaps, a local point of contact could be useful in Scotland as well?
Wikimedia UK is just getting going, so there's not a great deal going on beyond setup. If people want to use their initiative and come up with things to do, great, but it's going to be a few months at least until they can help out with existing projects (unless they want to help out with the setup, in which case, monitor this list and speak up if you have any opinions on the matters being discussed).
