Thank you 
Ashley for your efforts at helping get Opus support in Internet Explorer! I voted for:
- Ogg Vorbis and Opus audio formats support [Firefox and Chrome support it]
- a[download] attribute
- accessibility support of html5
- Apply the standards for just one time in your life
- APNG (animated PNG) images support [Firefox and Safari 8 support it]
- Native WebM
- Vibration API
- Web MIDI API
- webgl 2.0
I'd love it if others here would vote for Opus support in Internet Explorer, and help spread the word via Facebook/Twitter/websites.
