kdedevelopers e-mail feed, thinkpad KMilo plugin, proofreading and top secret KDE groups!
kde.me.uk has some things of mine on it.
kde.com's e-mail feed of KDE dot news died along with kde.com so I set up another one for dot news and added debianplanet.org and kdedevelopers.org. email news feeds. KDE dot news are planning on adding their own e-mail feed so that one may dissapear.
I made a KMilo plugin for Thinkpads which lets you use the volume and other buttons with KDE. KMilo is a bit under-documented so that page is also a general KMilo page, if you have a laptop with funny buttons on it (mine has volume, mute, brightness, keyboard light and one just marked 'Thinkpad') consider making a KMilo plugin for it.
I have a list of top secret KDE groups which for whatever reason (mostly good) arn't publisised. One of them without a good reason is the KDE proofreaders who now also have a page where you can add typos you find either in i18n() strings or documentation, ready for fixing once we're out of a string freeze.
