Cubby Beta, the best files syn service [Free Invite]

If you're using DropBox, Google Drive, Sky Drive or BoxNet maybe you like Cubby too. is a file-syncing service just like Dropbox, Google Drive, SkyDrive, and other cloud storage services out there, but it has two major differences that set it apart:
You can sync any folder—not just your main "cubby" folder—to the cloud and your other machines. Just right-click any folder and tell it to sync with Cubby. No symlinks, checkbox menus, or other tweaks necessary.
You get 5GB of storage in the cloud (that is, accessible from your browser), but you can sync an unlimited amount of data between your computers. That means if you want to sync your giant iTunes library, for example, you can do so without paying a cent.
Cubby is still beta, if you can't wait for try Cubby, comment your email here to get an invite.
