I've set up a subversion user list:
http://svn.wikimedia.org/users.php
If you have subversion commit access, please create a file describing yourself, at /USERINFO/<username>. The syntax is like MIME headers, see my example at:
http://svn.wikimedia.org/viewvc/mediawiki/USERINFO/tstarling?revision=21563
Current fields are name, URL and email, but I'd accept suggestions for more. The idea of the email field is to eventually set up aliases for everyone of the form <username>@svn.wikimedia.org. If you're worried about spam, I would suggest including your email address encoded with ROT13, in a field called encrypted-email.
