You have to first register for an on-site participation (step 1 & 2 – with technical tour) here.

After you have finished this registration process at the official fib page, we will send a very short form (before the end of August)to all the registered persons, in which you can indicate your priorities in relation to the technical tours. Based on this, we will assign you to one tour and inform you then accordingly with the last details.
