Hurray, because of money WowAce will now be Curse, and for a time , meaning months, as shit as curse is in it's current state.In addition, WAU will, for the time being, be discontinued as well as it won't be receiving any new content. In the immediate, however, WowAce's content will be available via the new Curse Client that is in development.
Not to mention, the WAU is crashing because wdnaddons.com don't exist anymore.
Which won't be fixed, resulting in the entire wowace repository more or less is unacceptable for a time.
Where do I find my addons now? *sigh*
