One down, two more to go. Bloody hell, I really needed the full 3 hours for that exam.
And while I should be revising for the next one, I added descriptions of everyone I certified... very productive indeed.
Last but not least, I proposed interfaces for an XPCOM XML-RPC client on the netscape.public.mozilla.xml newsgroup, and have started implementation. So far people are only listening intently (I get notified if someone adds themselves to the CC list of the Bugzilla bug I filed for tracking this), noone has offered any feedback so far. Thanks go to everyone on #mozilla that helped me out with my Q's though.
