Now that I'm home on my dev machine, I've resolved the issue preventing the slide links from showing on the DConf page. All the links for the slides we have are now available when you click on a talk's "Show Details".
I'm still waiting on the slides for 3 talks. I'll upload them as soon as I have them.
Once I upload the edited videos for each talk to YouTube, the links to those will also be available next to the slide links. I was hoping to start editing those in the next couple of days, but there may be a bit of delay. I currently have access to the recorded versions of the talks as they appeared in the livestream. But I'm waiting for news about access to raw footage from one of the cameras so that I can implement a consistent picture-in-picture format for all the videos. I'll start in on the editing as soon as I get word on that.
