Awesome. Some feedback: * When you click one of the lower videos, nothing happens. That is because what actually happens is that far far up, the video got replaced. But the user can't notice the action happens scrolled off-screen. Very confusing. * The brown link colours (e.g. link to "introductory videos" on http://texmacs.org/tmweb/help/learn.en.html http://texmacs.org/tmweb/help/learn.en.html) are almost indistinguishable from black text, at least on my monitor. It would be great to make them more visible, otherwise people won't find your good new material.
