Read what GTF says again and again, it is very true. Sometimes it's not a big deal, when it is, go online and check your bank balance. Weigh things up from there.
Remember this, you won't change anything in your time there, any contributions you make will be forgotten by lunch-time tomorrow,.....go online and check your bank balance.
It is a great experience, and you will be already half-way around the world, go see places.
