The relationship between Wikimedia UK and the WMF is one that people need to be aware of, but isn't one that people need to be afraid of. We (Chapcom) has a long history of allowing groups to organize in the way that makes the most sense for them, and running their charities in the way that they choose. I'm not saying it's impossible for us to rescind your chapters status, I'm just saying that it's not the kind of thing we do because it's a wednesday. Dont worry about us, if you set yourselves up in a good way for you, we'll probably be fine with it (minus the details, of course).
We're not worried about you, we're reliant on you to use those powers to make sure we don't have another failed attempt dragging on for years.
