You can scan written references as well as your police clearance, save them on your computer and then upload them to the 'My files' page in your Mindahome Members control panel. Email references can be saved as text or document files and be uploaded there as well.
Once you have uploaded them there they can be easily attached to the bottom of your profile page for download by home owners. You can also attach them to the messages you send. Please see the instructions on the 'My files' page.
