Newbie Terms (continuation)

Here is the next portion of NetLingo terms for newbies:

• RTM (Read The Manual) - proper netiquette on newsgroups calls for users not to post newbie questions that could otherwise be answered by taking some time to "read the manual";
• sig file (short for: signature file) - a short statement at the end of an e-mail message; it identifies the sender and provides additional information, such as an address and phone number;
• silver surfer - an adult, generally 50 years of age or older, who frequently surfs the Web and spends time online ("silver" refers to the color of their hair);
• snail mail (a.k.a. smail) -  regular postal mail; the obvious connotation of this term is that postal mail is slow;
• texting (a.k.a. texting, text message, person-to-person messaging, p2p messaging, SMS) - the act of typing and sending a brief, electronic message (less than 160 characters) via a wireless network to another person so that they can view the short message on any number of mobile or handheld devices, such as a Blackberry, a cell phone, a PDA, a handy, or a pager;
• troll (a.k.a. trolling) - online it originally meant the act of posting a message in a newsgroup (and later on a blog) that is obviously exaggerating something on a particular topic, hoping to trick a newbie into posting a follow-up article that points out the mistake.
