This is a reply to gknoy:

I would suggest Spider Oak, however, their support is not timely and there's currently a bug in the Windows 8 client that doesn't let it work. But if they get those issues sorted it could be a decent service.

Could someone please tell me why I can't reply to any comments that are below the third level? The reply link simply disappears!

Edit: Now that I've made this statement there's a reply to gknoy, but not the ones below him or to o0-0o. This is really weird.

Edit 2: Upon refreshing, there's now a reply link to o0-0o but not the other ones below gknoy.
