It’s been a while since I’ve signed up for a Web 2.0 tool. I think I’ve been going through some kind of withdrawal symptoms. Thankfully, I have a very cool and useful tool to pass along this time.

On more than one occasion, I’ve had to chaperone an overnight trip with a small group of students. Though I wanted all the students (and other chaperones – be they parents or teachers) to be able to get in touch with me in an emergency, I was hesitant to give out my personal cell number to a group of high school kids. Not because I didn’t trust any one of them, but because I know how kids (and sometimes parents!) are by nature. I always had this bizarre, uncomfortable feeling about letting my phone number be programmed into a student’s cell phone.

Enter numbr. You know it’s Web 2.0 since there’s no final ‘e.’ Numbr allows you to create a temporary phone number that forwards to your real one and, by default, expires after one month. According to their fact sheet, numbr’s vision is to keep communications from being crippled due to privacy concerns.

I’ve not yet tried numbr, but the next time I take a group of high school students out of town I’ll definitely be giving it a try.
