Hello, unfortunately one of my friends is not able to go to BM. Now I want to put one of the four tickets I bought back on the market, ideally via the STEP system (its "will call", I am in Germany). Is it possible to sell just one ticket or is it only possible to sell all four together? Can't find anything in the FAQ and didn't want to mess with the system itself in order not to "accidentally" sell all tix
. Help is highly appreciated!
