I proposed 3 sessions for Drupalcon Paris at the beginning of September, and just hope I can get one in. There's one on Debugging Drupal, one on Ctools/Panels Plugins, and one on Upgrade-proofing your site. Looks like they're all kind of low in the running, but they've all gotten some votes. Surprisingly the one that I thought would be the lowest ranked is the highest - the "Upgrade-Proof Your Site: Best Practices to Avoid Major Version Upgrade Headaches".
If you're going and you like any of these topics, thanks for your VOTE!
