Guess what? _**You're done!!!**_ Congratulations, you just \"finished\" your first rails app!
(They're never _really_ ever finished... have fun tweaking it!)
You get another sticker! :)
# Extra Credit
If you got all the way through Suggestotron with some time to spare, here's some extra stuff you can try:
* Add a downvote button that does the opposite of what the upvote button does
* Create upvote and downvote methods in the Topic model and use those in the topics controller instead directly modifying the topics votes
* Sort topics by their number of votes
* Add an 'about' page, linked from the bottom of the Suggestotron topics list. Link back to the Topics list from the About page so users don't get stranded.
* If your class has a **lot** of time left over:
* Users should be allowed to vote only once: give votes a user_id and allow a user to have voted on each topic only once. But wait, what is a 'user' in our system? Get a volunteer to introduce everyone to [Devise](https://github.com/plataformatec/devise), a simple way to add authentication to a Rails application.
* Users should be able to give a post a 'negative' vote instead of a positive one. How might you represent that in this system?
