Yes, please. I would like to be share work with collaborators and copy editors. And I would also like to share with members of my writing group.

Ideally, there will be limits to the sharing. For example, I would like members of my writing group to see my manuscript, and be able to comment on it, but not edit the manuscript itself.

And I would like copyeditors to be able to see the manuscript and suggest changes, but not edit the manuscript itself. And then, ideally, I would have a way to approve those changes, such as spelling or grammar corrections.

I also very very VERY much want to see online access. I would like to be able to work on my manuscript from a phone or tablet.

Right now, I'm using Google Docs which allows all the collaboration options I mentioned -- both comments by other writing group members, editing suggestions by copyediting, or full access -- as well as mobile access.

Google Docs also keeps unlimited versions of the document and tracks all the changes between versions, which is super useful.

One option could be to make Granthika a Google Docs plugin. I would definitely pay extra for that.
