Most email providers have a limit on the size of files you can attach to your emails. I believe that Google, Yahoo and MSN all allow only up to 10MB size files to be sent. So what do you do if you have larger files to send? Maybe give a try out to: YouSendIt. I gave it a test this weekend and it works just as advertised. Send up to 1GB attachments for free. Simple and secure, it's worth a bookmark.
