We write short stories for you on the fly. About one or two sentences long. And send you an email now and then asking you to read them. To then do your best to remember the names and places given in the stories.
Once you've read a story, a quick test of two questions will be sent your inbox within a random period of time. The test will reward you points if you remember the story correctly. You will notice that your short-term memory will get better and beter by doing these tests on a daily basis.
