My students would love to communicate via web 2.0 tools with students in Mexico. They want to practice Spanish and maybe your students could practice their English.
A shared Ning would work well!

I might be able to help you out. Im the lab coordinator and closest thing to a tech guru at my school. We have a high school and a university-level division. Ive been pushing the use of Web 2.0 tools here. Contact me at leigh@itesm.mx and let me know which level you prefer.
