I hate people who send 5Mbyte attachments or larger in unsolicited email messages. I didn't ask for it; why are you sending this to me? Moreover, I'm not the only recipient. Several colleagues have also received the same information, and the same 5 MByte attachment. Great.
Are these people paid on commission by our enterprise storage supplier, or our ISP? Wake up. STORAGE AND BANDWIDTH IS NOT FREE. Do us all a favour and stop abusing email.
Email is a wholly inadequate a medium for distributing big files. Such large files could simply be downloaded from a website. If you must email me, just send over the link and an explanation note or whatever in plain and simple ASCII - no need for logos, graphics or formatted text either. Thank you.
