I just joined the list on reading the http://meta.wikimedia.org/wiki/Wikimedia_UK page. I am very interested in the promotion of open-source knowledge, and educational use within the UK. The prospect of a UK chapter is very exciting.
I am the owner of http://wikipedia.org.uk, mentioned on the page. I registered it to avoid unfriendly squatting on the address and would be willing to assign it to wikimedia-uk at whatever point it becomes a legally recognised educational charity, and redirect it as required up to that point.
