My flashcard site, Quisition has now been moved over to WebFaction and I took the opportunity to clean up some code and make some incremental feature enhancements.
You can read more about them on the Quisition site. One new feature is the ability to reset long overdue cards. So if you tried out Quisition a while ago and would like to come back without a huge backlog of old cards, this feature is for you!
I've also implemented an alpha version of the testing parts of the site specifically styled for the iPhone. If you're interested in trying it out, email me and I'll tell you how to access it.
