I was about to take the challenge 

Get started with predictive analytics

Read this:-

1. Go to Azure Machine Learning, and click the "Get started now" button. You will need to sign-in with your Microsoft ID - please use the same one you use to access your DVLUP account.
2. Once you have logged in, search for an example experiment. (such as Binary Classification)
3. You will then open that experiment in Azure Machine Learning Studio and train the selected predictive model by clicking the "Run" button at the bottom of the page.
4. After this experiment runs (it will only take a minute or so), click the "Create Scoring Experiment" button at the bottom of the page. Follow any on-screen instructions, as needed.
5. Click on the "Publish Web Service" button at the bottom of the screen to publish your experiment.
6. By clicking on the globe icon in the left-hand side, you will then see the Web Service URL and API key for your experiment. Now, take a screenshot to include the "experiment created on xx/xx/xxxx" and the full web page.
7. Post your screenshot to either Twitter or OneDrive and include the link in the Comments for us to validate. You can find a screenshot example posted on Twitter @dvlup :

So what actually do i have to post as the comment?

the azure webpage or the tweet

And how can i do it using onedrive?

Thank You
