We don't use our Disqus comments anymore to share videos or uploads, BUT we've found an easy way to use YouTube to share your videos. You can either use your smart phone and upload a video using the free YouTube app, or you can go to YouTube My Webcam and upload it directly to YouTube from your webcam as long as you're already logged into your Google/YouTube account. Make sure to add #fi3m to the title of your video (e.g. French Day 1 #fi3m) so that others can find it and comment on your progress.
If you're not comfortable sharing videos over social media, don't sweat it! But make sure to demonstrate your speaking progress to someone in person, it helps you step out of your comfort zone a little bit and make that first step to speaking with a native.
