Hi there Burek and welcome on the forum. Usually at RPGVienna new players should start with level 1 characters and level their way up the ladder so to speak, afaik. I have no problem with you joining my table right out the gate with a lvl 3 character however. I look forward to seeing you at my table tomorrow.
P.S.: For character creation outlines at our V.A.L.U.E. games, I recommend you quickly check out our houserules at this link
