Here are the two surveys:
Note: if you access session evaluations from individual sessions in DevCon2Go, each session code will be populated automatically for you. To do this:
1) View the session detail in DevCon2Go
2) If on iPhone, tap the More... button
3) Tap the Rate Session button
I just added individual survey links to this page here in the FM Community:
Now you can just work your way down the page looking for the sessions you attended. When you click the link, the survey will be populated with the session information -- faster than using DevCon2Go.
There's a second page organized by track as well.
