For those people that are using your GMail accounts for file storage then you might want to grab this update to GMail Drive (if GMail Drive is what you are using, there is also a Firefox extension that does this). The GMail Drive update fixes a bug where it would tell you that there is no room left to upload files, but in reality you would have plenty of room. This is because Google changed some code around which screwed things up in the software, but it is good to go now!
If you are using your GMail account for file storage then you may want to create a separate email account for doing this. Google is known for terminating accounts that they find to be using this software (especially if you use it excessively).
