I went to Cram to have a look at the site, signed in with my Google ID and in 5 minutes had a flashcard set with two cool game options as part of the learning. Could not believe how easy that was and how much fun. Cram has 108 million flash cards at the moment divided into logical learning areas. The more people add to it, the more choices we shall have. There is a premium version of Cram if you are interested. I am not a big flash card user but I have looked for a long time for a site where I could just make some sets of vocab cards. Repetition is how we memorise and so, with technology, we have to find different ways to get the repetition going. The two games which are part of the learning activities are a nice bonus.
