Yes, I have an e-mail address to share: email@example.com. That will always be redirected to the president of the Dutch Chapter, which, for now, would be me.
Best of luck launching the new Chapter in London. We are Headquartered in Leicester Square if your looking for venues.
happy to share our experience of managing the North East of England chapter, which we started with a small handful of members to now 100+. Drop me a line if you have any specific queries, I will also be at the secure summit (London) in December if you are there...
