Finally, we've created a Wuala group in Wuala :) We'll add some content there over the next weeks. To start with, we have blog and press reviews, faq, photos, and the release notes (the new place for changelogs :). What else would you like to see there?
Most importantly, however, the group is for you to participate. You can post bugs, screenshots and ideas directly into the appropriate folder. We'll check them frequently (hey, after all, we get a green notification ;-) and copy urgent ones over into our internal Wuala group.
Once the group has interesting content (and ones the UI scales for groups to have thousands and thousands of members), we will notify all users. For now, we don't push it.
