  26. Guidelines • Check eLinux.org past events periodically • Follow links to events • Look for interesting stuff • If information (presentation or translation) is missing, ask about it on celinux-dev@tree.celinuxforum.org • If you are really kind, try to see if it’s already linked to from an appropriate area on eLinux.org • If not, link it!
