Tell not to worry for detail URLs not working.

I notice that if you click on a party link in the list you get a correct detail page, but if you open the same destination URL in a new browser tab, you will not get the content. Worrying that the whole scheme could be broken, I checked final app at step 22 and it had correct behavior. I checked on further steps and noticed if was fixed in step 10 "Privacy & Subscriptions", section "Subscribe with Params". Some other users of the tutorial will get worried, too, this change fixes that worry. Thank you for your attention to details and tutorial quality.
