Carsonified are the world leaders in creating and managing events for the web community. They have also created a number of web applications to help web designers and developers. The latest web app that was released is Think Vitamin Membership. The membership gives you access to an ever-growing array of tutorial videos on a range of topics including design, html5, css3 and jQuery. Depending on which level of membership you go with you can also get access to their amazing online conferences and also videos from their Future of Web Design and Future of Web Apps conferences.
This membership is fantastic and I recommend it to any designer or developer. Make sure you head over to the Think Vitamin Membership page and watch the example tutorials they have available.
