To do this, you should conduct a search. This is accomplished by first signing in to your account, then choosing ‘Community’ and ‘My CBANC' from the menu near the top of your screen. You'll then be presented with a search box, into which you can type some key words that will hopefully yield results to match your query.
Clicking on any of the results will give you the option to download the document to your computer. In cases where the exact document that you require is not available on the network, you're invited to ask the community. Another member might have just what you need. To ask the community, click the 'Start Discussion' button in the bottom right-hand corner of your screen.
