How I got them was:
1) Used the files page to get the zip
2) Took the empty folders OUT of the !!!Standalone folder and put them in my Addons folder, with the rest of my addons.
3) Used WAU to update them as a regular Ace Addons - I use the RSS feed to watch when they get updated as well
I used the AceZips files page to get the original !!!Standalone as WAU seems not to like to unzip empty folders.
