Pros
Amazing experience, friendly staff, challenging tasks and lots of fun. You can practice English as well as other languages while meeting interesting people at the Forum 2000 Conference. Whatever might change, they always let you know as soon as possible. They always come up with a solution how to get you involved - even if you are still in high school. If you're interested in NGOs, this is the job!
Cons
You need your own transport and accommodation in Prague if volunteering at Forum 2000 Conference.
