I am a little nervous about this, but...
I'm ready to open up DataPipe for beta testing. DataPipe is a service that will send data from your behavioral experiments to the OSF, for free.
Don't use this for critical data collection yet. It might have unexpected outages during this final round of pre-release development. But, if this is something you might be interested in using once it is ready for stable use, please try it out and let me know what can be better.
