Thanks to Bud (and some very good advice and input from a lot of others) I am very close to getting this project off the ground. I am getting my students registered for Moodle. I am hoping that from there we can conduct our web searches, post some examples of good and bad web writing and generate some discussion toward the creation of our class rubric.
I may also be looking into 21publish as an option for posting our actual discussion about A Tale of Two Cities. Bud has suggested that it might be easier/better to keep everything in the same format which is probably true. I figure it will be worth it to at least check out 21publish to see how it works and if nothing else, expand my options for the future.
So thank you for everyone who's helped me with suggestions and ideas so far, I'll let you know how things go once this thing gets rolling!
