[Koha] [koha] new user

Hello! My name is Lukas Szymanski, i worked in Public Library in Kolbuszowa, Poland. Our Library want to use the Koha system. We are alredy using Marc and i want to ask about yours experiences in using Koha with Marc. Is this works correctly? I think if I could help you in work over Koha or polish translation (i'm much better in translation to polish then writing in english :)). Maybe I could help in php and mysql programming? Yours sincerely Lukas Szymanski
