Aha. This should work for “Community” on its own (although in Google reader it’s coming up as only “Website and forum”:
http://arduino.cc/forum/index.php?sa=news;limit=10;action=.xml;type=atom;board=24,25,26,27,28,29,30And I get only the initial post on each one.
[edit]: Hmm, yes it is only paying attention to “Website and forum” — for example, the “first post” entry in ”bar sport” isn’t present in the Google Reader list.
[further edit] aha, and if I increase ‘limit’ to limit=30, I pick up all 14 original posts but only in “Website and forum’. However, if I reverse the order of the ‘board‘ value list to board=30,29,28,27,26,25,24 what I get is one post only, which is the “First Post?” entry in “Bar Sport”. Interesting.
