Also remember: there are phones hooked up in every dorm room, and unlike your cell phone they are guaranteed to have reception. As it says in the Precamp Briefing, you need to buy a phone card to use your room phone for outgoing long-distance calls.

Other electronics. The number of small electronic devices is proliferating, and their power is growing: MP3-player, iShuffle, iPod, iPod-touch, iPhone, iPad,.... Many students own one or more.

The same general rule applies to all these devices:

1. They are easily lost and we are not responsible for the cost if you lose them.
2. Email and webbrowsing is available in the computer lab in our dorm, so you should not bring a handheld device just for this purpose.
3. We don't want these devices to get in the way of engagement with mathematics or engagement with other campers.

• Playing computer games at any time.
• Listening to your device through earphones in the dining hall or any other place where this will keep people from talking to you. (Listening to music as you drift off to sleep in your room is fine.)
• texting in any public place.
• Using any of these devices at all in a plenary or breakout – unless you are using it as a calculator with the consent of the lecturer or breakout instructor.

If you don't use any of these devices regularly, and are not already used to keeping track of them in new places, then leave them at home so you don't lose them. If you must bring them, as with cell phones make sure contact information is built in unerasably.
