Sparks work a bit like upvotes or likes on other social platforms, but with a much more specific (and important!) purpose on Packback
Sparks are given to posts which truly “Sparked your Curiosity”, to show appreciation to the original writer and help the community recognize the most curious posts. Sparks also help other students recognize posts that have been inspiring to their classmates and gives professors valuable insight into what their students are most curious about.
To give a Spark to a question or response, simply click on the light bulb icon on the top right-hand corner of the post. When you have successfully added a spark to a post you should notice that the spark count has changed and the icon will remain illuminated.
Keep in mind that as a student your sparks will be limited to 5 sparks per week. Once they are all gone you won't be able to spark any other posts until the following week when your spark count resets.
