Though it uses a font that children *might* read in various text sources, my only criticism thus far is that as you try the site out for the first time, letters such as "g" and "a" don't appear as children will write them, but never fear, the font can be changed to something more compatible, like Comic Sans if you click on the settings tab. Teachers and families will likely want to fiddle with the settings before having their students use the site.
What other online reading resources do you recommend for your students?
