Our parish wont open google sites, but they did open Edublogs. You can have one page with all students contributing or individual student blogs. It is free and if you need more storage space it is $20. All the bells and whistles is 40 a year, but many just keep it for free. If you go to edublogs.org and look to the bottom right you will see several blog links to visit. thedublogger.edublogs.org is another great first step!
