To keep notes and ideas like those from the conference organized I use Evernote. It's a free program that allows me to type, organize and store notes on-line so they're safe and always accessible. It's quick and easy to use. For the ACA conference I created a notebook where I put all of my notes and ideas for future reference.
I use Evernote almost every day to keep track of meeting notes, discussions I have with staff members and ideas that I want to capture. It's a great tool for helping me stay organized and productive.
