Hi and

to disABILITIES!
If you click on where it says "disABILTIES" at the top of this page it will take you to the Index. One of the top items is the "disABILTIES FAQ" which will gives lots of useful information. Go to Post #3 and scroll down to where Oxygen is discussed for a lot more details.
But basically you need to talk to the Social Services person at your current supplier and they can handle everything for you.
Or, if you want an easier route to the FAQs, click on the link in my signature.
