Megirtam elso postcrossing-os levelem, de elfelejtettem, hogy a postcarc ID-t nem a cima al kell irni. Mit tehetek? Feher javitot lehet hasznalni?

DO:

do write it on the left side of the postcard (direction of text is unimportant)

do write it more than once on the postcard

do double check that you wrote it correctly

DON'T:

do not write it under or to the right of the address

do not write it next to the postage
