You can enhance the Hub content by adding your own notes to an item.For example, it may be that local practice differs from the advice on the Hub and you want to add a reminder. If you are a member of a Group your note will also be visible to your colleagues so you can share knowledge and insight with them.
To add a note click on the 'Make a note' link in the r/h panel as shown below
Then type into the yellow note that appears on screen.
You can browse any notes you have added by using the drop down list under your name (once you have logged on) and selecting 'Browse notes' as below
To edit or delete a note, once you have opened the item, click the 'Make a note' link again. This will open up the note box for editing. To delete the entire note, simply delete all the text.
