2Large2Email

You've got a 50Mb sales presentation PDF you need to send to your remote office, pronto. You try to send it through Outlook. It bounces because it's too large.
You grit your teeth, and try again. It fails. You're about to start tearing your hair out when Joe in the cubicle next to you tells you about 2Large2Email.
You log on, attach the file, type in the email address of the client and hit send. So easy.
