Hi all, A little intro first, I'm a developer by day, sql/plsql/java/perl/c/c++/... I've been looking for an opensource project to get to know and contribute to and came across twisted a week or so ago. It looks pretty interesting, years ago I spent time writing networking/remote access code.
Anyway, I want to help and am starting to look through the 'easy' bugs - Python is pretty new to me so I figure that's where I should be. I took a look at http://twistedmatrix.com/trac/ticket/4966, which might be out-of-date. I don't see __all__ in twisted.web.server.py. Am I missing something there? Also, does the email verification on the website work? I've tried it a few times and haven't received an email, also nothing in my spam/trash related to it - sorry if this shouldn't go to the list.
