In October 2009 the Quebec French part of the international SMS4science project, called texto4science was launched. Over a period of 10 months, we collected slightly more than 7,000 SMSes that we carefully annotated. This database is now ready to be used by the community. The purpose of this article is to relate the efforts put into designing this database and provide some data analysis of the main linguistic phenomena that we have annotated. We also report on a sociolinguistic survey we conducted within the project.
