Just got my CVS account on cvs.openbsd.org; it came totally out of the blue when they gave me the offer, and took me about 0.0000001s to accept it :-) I've just been hacking away at random ports so far, but I'm gonna figure out how to get organised and do stuff.
Looking forward to working on the OpenBSD ports tree, and hopefully helping out with this unified BSD ports system whenever that comes about.
