I have been called rather worse than paternalistic on wiki and elsewhere:)
The offer still stands, but rather than leave Carrite's thread as the only response I will take the opportunity to expand on it a little. London, for reasons obvious and otherwise is one of the centres of the wiki community, It isn't just a city of 8million, there is a much larger population who are in commuting distance. I am a regular at the London meetup and I'm also part time staff at Wikimedia UK. I know there are quite a lot of admins and other functionaries in or near London. I am in a position to convene and promote such an event, and arrange space at the chapter's office so it can be hosted for free at a convenient location in central London.
Wikimania is about 6 months away and will only get a subset of the audience you want for such a session, albeit an even bigger subset than London. So running an event in London would mean starting a diversity training program much more quickly than starting it at Wikimania, and an extra chance to get the content of the event right. If the London event shows that for example you aren't yet clear what changes you want people to make in their behaviour, then there could still be time to get that right.
So if someone is willing to run a training session in London then please get in touch on or off list. Otherwise I would be obliged if someone could give me a link to a page which explains what diversity training for wikipedia admins would involve.
i concur
we need to be open to people, and team with them based on conduct
this remark tends to play into the negative stereotype, which is not what we are about.
