In a month, one can not store more than they're allowed to upload. Correct me if I'm missing something, please.
That is correct, however, the actual storage size is unlimited. For example: if I uploaded my very first note on January 1st, but reached my 60 MB 'upload' limit on January 25th, I cannot upload another note until February 1st when the upload count resets. The notes I uploaded in January will still be present and available to me, and will not count against the 60 MB upload amount for February. I hope I made sense with that. Sorry for any confusion.
