It is so easy to set this up that even my 94 year old grandma could do it...ok just kidding she totally could'nt do it, but I am confident you can.
Step 1: Go to https://cart.rackspace.com/cloud/
Step 2: Select Managed Infrastructure and fill out the rest of the fields (Remember the username you choose, you will need it later) then click next.
Step 3: Fill out all your address information, then click next.
Step 4: Fill in your credit card info (don't worry you are not buying anything yet), then click next.
Step 5: Once it is done building your account click on Activate my account.
Step 6: Once you are automatically logged in, then at the top right click on Account and then Account Settings. Just in case something went wrong and you were not automatically logged in then simply go to https://mycloud.rackspace.com/ and log in there.
Step 7: Once you are logged in under the section Login Details you will see an item called API Key click on show and copy that long key to your clipboard.
Step 8: Login to your WA Nexus account and under the section User Accounts click on the main admin account which should be the account you setup originally with WA Nexus.
Step 9: Under your account details in WA Nexus enter in both the Username and API Key you copied and then hit Edit ... and you are done.
Was that so hard?
The awesome thing about Rackspace Cloud is that you will only pay when you use it. Like I have mentioned it is very cheap to use this service which is perfect for small churches.
