I work in the area of L2/L3 influence on native languages; will you be including the influence of other acquired languages on the Spanish? My colleague at work is from Puerto Rico, and she says that the people of the interior of the island use their pronunciations and constructions from Taino when they speak Spanish. I am also interested in whether or not you are asking the participants if they use texting language/mobile phone language - even I have noticed that I am beginning to use texting constructions in my speech patterns. Best of luck!
