I volunteered with this children's organization for 5 weeks, and it was an amazingly fun and enlightening adventure. If you're looking for part-time volunteering (which I did as I was living across the city), or if you want to do it full-time, it's so easy! I know you're supposed to do it all official online, but I just emailed when I arrived and they were happy to take anyone. I helped with photography, the website, and record keeping. You can lead activities, or teach English and computer skills! They need help at the orphanage and at the local school, but also appreciate help in marketing if you've got the skills. This organization is like a family- and I keep in touch with everyone from the founder to the field manager to the volunteers. And the kids make it all worthwhile. Find out more at www.help2kids.org!
