It's called PanelPicker for a reason - starting next Monday, August 19, you, the voting public, will have a chance to pick your favorites, and not-so favorites from the panels submitted to SXSW Film.
Public voting results constitute 30% of the final panels lineup, so your vote really does count. It's a simple enough process - simply set up an account, sign in, then make like Ebert & Roeper and rank panels with a thumbs up or a thumbs up, commenting as appropriate.
Don't forget, if you want to attend the panels next March, you need to register for a badge - head here to find out how.
Read more at the PanelPicker FAQ, and brace yourself for Monday - it's time to rock the vote!
