Funny you should ask.... I recently created a blog precisely for this purpose--to collect ideas for students of all levels, both with and without internet access (but mostly with, I think), who would like to go on learning outside the classroom. It's called English Power, and it doesn't have much yet, but I hope to add more as time goes by.
Thanks for inviting me to this blog. Hello to my friends from Senegal whom I have met at WATESOL conferences!
