If you would like to devote your services to the United Nations Volunteer Services but cant be present onsite- here is some thing you can do online for the world- NetAid. You can devote any kind of online service to poor people and nations all around the world- just sitting at home. NetAid helps by connecting people who would like to "do more" to support the poor in developing countries, with groups and projects in the developing world. Two flagship programs of NetAid are NetAid World Schoolhouse and NetAid Online Volunteering
Let us join the fight against poverty!
