I have been on this site for a very long time, with each day the site is getting better but what is still missing for me on this site is translation. This is becoming a barrier but there is an easy solution for that. It can be easily solved by giving an option to translate the message automatically. For example person A is an English speaking person and person B is Spanish speaking person, when person A is sending message, the message should contain a translated version in Spanish for person B and same goes for Spanish speaking person.

P.S. use google translate api to do so
