I know that Gmail provides its users with a gagillion MB's of space but let's just be honest: It is very possible to use up that space with random funny emails coming through once a day from a thousand friends.So what do you do?I found this post that explains how to constructively search for larger emails in your Gmail inbox.By simply searching your Gmail search for the term "has:attachment" your results will show every email with an attachment. As you can only imagine some of these attachments are random funnies from random friends who have nothing to do but email .wmv movies to everyone in their inbox.Other effective search terms include: "filename:pdf" or "filename:xls" and various variations of the like.Try them out and flush out those pesky emails taking up all your space. What a pleasure.
