If you have thoughts about things that went well at WisCon 37 or things that went not-so-well, we’d love to hear from you. We have a general survey as well as a survey about programming.
Lastly, if you have programming ideas for WisCon 38/SFRA, you can submit them now.

ETA: If you’re coming here in May 2014, this is an outdated post! The post with links to surveys after WisCon 38 are here.
