For this online space we wanted something more descriptive than "discussions" or "forums." The name also needed to be short so the web site address did not grow to be too long! And we wanted a Spanish word.
Before we left Guadalajara we asked a number of people and it was Kike who suggested "dilo" which he translated as "Say it" -- this is very fitting, a place where can "say" things, openly, but also where we have different levels of places/groups to speak.
How does this work for you?
