It is important to learn how to attach files to emails because it it is an easy an convenient way to send your ideas and presentations around to people you know. it is quite handy in the business world. My dad would know he works for Trw and when he has to file the reports about what the customers are ordering, he usually sends the word document or excel or whatever via email. if there is no Internet, then he uses a fax. he always has a plan.I don't know if he sends any via bcc. He should. He uses his laptop at the house every now and then to look at outdoor gear from Realtree or Bass pro shops. He could pick up spam and send it to is superiors through email. YIKES! I'll remind him to send bcc from now on.
