 Most people have created or translated some sort of written work whether fiction or nonfiction, published or available to read online for free.Penpals have been popular since Esperanto's earliest days, as Esperanto was originally advertised as a language where you could "send a letter with a message, short list of grammar rules and a dictionary to a complete stranger, and they'll be able to look up the words and write a coherent reply back".Many people did indeed do this in order to recruit more Esperanto speakers.
