Hello, I had to reflash my N9 because of many issues not concerning wazapp.
Yesterday I tried to reinstall Nightly version, but the link found on the wiki is not working anymore. Is Nightly version not more available?
Now I'm using last official version, and registration went perfectly fine. So having access to nightly version would be appreciated, but it's not essential for me now, especially after reading all that is happening with whatsapp and BB... :/ I suppose that all developpers have something else to do now.

So keep up the good work, and hope wazapp will still live long on our N9 (and who knows, on other OS)!
