I’ve seen many teams using Mingle as a card wall instead of using real index cards. Usually the teams are distributed, so real cards wouldn’t help anyway. They all run into the same problem that Mingle doesn’t have a feature to automatically refresh a page throughout the day as the team updates cards. I’ll show you a few simple solutions you can choose from to refresh Mingle automatically.
A quick and easy solution is to use a Firefox extension that can automatically refresh any page called ReloadEvery. This is probably the least amount of work and works just fine.
