We have added a new feature on the site... Reading History.
This is a special collection that you have to opt-in to use. It shows you the last 50 stories you've read for 30 days. (stories will drop off the list if they are there over 30 days. The oldest will drop off if you have more than 50). The history is not public. Only you and staff can see it. As you can see from my screen shot, it also shows you the last chapter you've viewed and gives you a link to it.
The plus sign allows you to add a story to a collection directly from your reading history, if you want to save it long term. The red X box allows you to delete the story from the history.
IF you want to remove the entire history and stop tracking, go to "Manage" and then choose "Delete Collection".
I know a lot of people have been asking for this and I thank everything for their patience is getting it implemented.
