Security is a huge issue for web users. Every web user (this means you—if you’re reading this then you are a web user) should be careful about what information he discloses. You should be careful about telling the world where you are all the time. You should be careful about your passwords (change them, don’t use the same one for everything, don’t make them obvious etc). You should be careful with your email address and you should be careful with the email addresses of others. This brings me to my rant of the day. When you send a mass email (e.g., change of address or some other notification) to your friends, colleagues et al please use BCC (blind carbon copy). In any email software or online browser-based webmail program, there are a couple of places to put the “to” addresses. When you put addresses in the CC (carbon copy) line, all the other recipients can see all the email addresses to whom you sent the post. When, however, you put those addresses in the BCC line, only you can see them. They are hidden from everyone else. Generally, when sending a mass email it is considered good form to use the BCC line. Put yourself in the first “TO” line/box and then put every other address in the BCC line/box. Why? It helps reduce spam. Just because someone sent their address to you does not mean they wanted that address sent to 3,000 people whom they don’t know. It’s a courtesy. It doesn’t take any longer to use the BCC line/box than to use the CC line/box. Most of the time this happens because the sender wasn’t conscious that it could be an issue. Well, now you know. You’re welcome.
