I know that there is a thread about trail angels but can't find it right now . So here is a reminder:

An updated list of trail angels is here. 

In the guide there is a short one page list of trail angels from mid 2008. Since then the list has multiplied by an order of magnitude and it is continuosly updated. It is impoprtant that you have with you an updated list of trail angels or access the list when you are on the INT.
