We're discussing some options. But, the truth is that when you start having guests w/ Q&A sessions, presentations, etc. - things tend to be removed.
The trading session last year was bumped entirely due to how long it took us to get everyone in and registered. Since we have online registration this year, and have a "plan" in mind for the lines (multiple) it should free up some more time during the day for things like trading sessions, etc.
The other option is to have a trading session on Friday night now as well. Like I said, we're discussing some stuff.
