With BoardPro's Annotation feature you can mark documents as "Read" as you read through them.
When the board pack is opened in Add My Notes on the left hand side is a list of all documents that have been uploaded into the board pack.
On the bottom of each document is a "Mark as Read?" box. When you have finished with that document -tick the box to mark that it has been read. A green Read box will now be shown.
This is especially handy if you have a large number of documents to read through.
