Problem with email
My email (Gmail) on my iMac is giving me an error message: "Mail cannot save information about your mailboxes because there isn't enough space in your home folder.
Quit Mail and delete any files you don't need. Then open Mail again. (then a quit button, which CLOSES the mail program.)
HOW or WHERE do I delete files in MAIL ???
