I'm having fun going through dictionaries to find Esperanto terms for various terms related to current technology, I've been successful with browsing, blogging, YouTube, nearly anything with social networks (via setting my Facebook language to E-o), Q&A sites, etc. One term that eludes me is lonely hearts (I hope I got it right in English!), a website or magazine column where you can advertise for finding a relationship.
I would guess at some combination of -il- or -ej- with am' or with koramik' or with renkont' but I experimented around and it never really expresses the meaning.
