[Very sorry if this is not in the right topic, I thought about it like an 15 minutes where to put this question, decided to put it gere, but not 100% sure.]
is here any rule about the usage of the word “Postcrossing” for commercial purposes?
For example if I would want to print my own postcards with some picture which I designed and with the text “Happy Postcrossing”, may I do it? In the case that these postcards will not be just for my personal purposes, but for selling. The same example, but with stickers with text “Happy Postcrossing”, printed for commercial purposes. May I, or is it forbidden?
I know that here is the rule about usage of official Postcrossing logo, I read the page about it on Postcrossing website, but now I am not sure if there is any rule about the word “Postcrossing” itself. Like when I will make “my own visual design” of the text of this word.
Can anyone answer me, please, and ideally back up an argument for his answer?
