"If you had con'd that mob before attacking it, you'd have known it was suicide."

You should use the consider command as a good way of guessing whether you should attack a mobile. Usually, it will take into account your current equipment and level, but not your status in general (i.e., hp, mana). Often, consider will only compare your level to your opponents. This command is sometimes buggy, so be prepared to flee if you have not fought the mobile before.

  10. Yahoo! Wild Web Rides, p. 157: Some MUDs will allow you to simply type quit to log off. That's it. Will you have your stuff when you come back? That depends on the MUD. On some you'll keep your stuff, on others you'll only return with part of it, and on some really painful ones you won't come back with anything. (You'll return with your money, though, so sell the stuff you have before you leave.) Other MUDs may require that you rent at an inn. This will usually allow you to keep your stuff, but if you're a long way from the nearest hotel you could be in trouble. Some rent is free and some will cost you a certain amount of money per item. This can be a pain, but sometimes it's your only choice when you think the MUD is worth it and you want to keep your stuff.
