   ### STEP 1: Request a user token
   $cred1   = New-OAuthCredentials -Type RequestToken -SignatureMethod HmacSha1 -ConsumerKey $ConsumerKey -ConsumerSecret $ConsumerSecret
   $client  = New-RestClient -Cred $cred1 -Authority $Authority
   # $client.AddField( "format", "xml" )  ## this doesn't work for some reason
   $request = New-RestRequest -Path $RequestToken

   $RequestResponse = $client.Request( $request )

   ##############################################
   ### STEP 2: Get the user to verify that token
   $RequestAuth = [System.Web.HttpUtility]::ParseQueryString($RequestResponse.Content)
   $AuthURL =  "{0}/{1}?oauth_token={2}" -f $Authority.TrimEnd('/'), $Authorize, $RequestAuth['oauth_token']
   Start $AuthURL
   $AccessVerifier = Read-Host "Please enter the token from the web site: $AuthURL"

   ##############################################
   ### STEP 3: Get an access token
   $cred2   = New-OAuthCredentials -Type AccessToken -SignatureMethod HmacSha1 -Verifier $AccessVerifier `
                 -ConsumerKey $ConsumerKey -ConsumerSecret $ConsumerSecret `
                 -Token  $RequestAuth['oauth_token'] -TokenSecret $RequestAuth['oauth_token_secret'] 

   $client  = New-RestClient -Cred $cred2 -Authority $Authority
   # $client.AddField( "format", "xml" )  ## this doesn't work for some reason
   $request = New-RestRequest -Path $AccessToken

   $AccessResponse = $client.Request( $request )
   $AccessAuth     = [System.Web.HttpUtility]::ParseQueryString($AccessResponse.Content)

   ##############################################
   ### STEP 4: Now stash that stuff somewhere!
   $credentials    = New-OAuthCredentials -Type AccessToken -SignatureMethod HmacSha1 `
                     -ConsumerKey $ConsumerKey -ConsumerSecret $ConsumerSecret `
                     -Token  $RequestAuth['oauth_token'] -TokenSecret $RequestAuth['oauth_token_secret']

   return $credentials
