A wonderful FREE site for teachers to collect and store all sorts of curriculum work is a new start-up called - Coursekicker.
There's much more to Coursekicker. It will take some time to look through it and see what parts apply to you. For example, there is a Community page for educators to share together by posting questions, challenges, discussion topics, etc..
It looks like Coursekicker has the potential to be a wonderful resource for all teachers on all levels.
Let me know if you check it out!
