Good news! Consider to make possible for user to click on .ics so they can easily add to agenda. Have this published on Maemo.org under the announcement, and also have an agenda specific subsite. In current design it'd fit on the right of the website I'd say. Or even allow subscribtion over WebDAV. Here is an example of .ics (must unzip it first since .ics not allowed to upload). This is also great for other events, and in the future, perhaps even deadlines. Ofcourse approx still means approx. Especially useful if Maemo 5 can handle iCalendar.
