I am attending php tek12 next week. One thing that I think the tek team should do is make it super simple for me to choose the sessions that I want to attend.
My vision: Since the majority of each session on the schedule page is a link, maybe add a check box/radio bottom for each time slot. This would dim the other 2, making the ones I want to attend standout. The printed version would look nicer.
Also, if I am logged into phparch.com, a simple ajax call to store my choices, so when I came back, it would be all preselected set for me. And I could make changes if I wanted to.
Probably a little to late for tek12, but there is always tek13 🙂
