After this year, Wuala will no longer be free. So far it served the project pretty well as a collaborative repository when it comes to making and storing various assets, like blend files.

Currently the repository takes about 7 gb of space and it's not even big yet. Considering current amount of donations to the project (next to nothing) and my income from freelancing (tiny) and savings (minus) I won't be able to purchase a paid subscription. https://www.wuala.com/en/purchase/storage
Before Wuala, I used to use Dropbox, but it's not that nice. Might consider getting back to it if I can't find another alternative that I'm happy with. Might even contact github and ask them to increase the space quote and host more stuff in the project repository or in an alternative art one perhaps.
Anyone using cloud storage services for collaborative games and assets?
