Here are several tools that I used in this class which I think it is pretty useful to everyone, so I post them here and hope you will enjoy.
No.1 Google Docs
Google docs is the best tool that I use for online editing. Every person I invite can edit the page, it is super convinent.
No. 2 GroupMe
This is not a new tool, I have use since years ago, but it’s still effecient, it is similar with text but can support a group to text together.
No. 3
I will keep upload my experience with advance tools I used, thank you
