W3C Technical Plenary / Advisory Committee Meetings Week
The W3C's global audience is thankful to speakers for following those essential guidelines. They are crucial because they transcend language barriers, foster comprehension, provide people the time to get acquainted with the subject by reading the slides, in some cases translate them into other languages, in some cases share and discuss them with colleagues before traveling to the meeting.
Below are the principal guidelines, which can be read in full in the Speaker Resources W3C public wiki.
Feel free to ask Coralie for help, including putting your slides on the Web.
