WiZiQ

There are a lot of sites these days upon which you can host your own tutorials and publish multimedia files. WiZiQ seems to be in a new phase (and consequently seems to be down a lot for 'development' at the moment), although it has been up and running for a couple of years.

You create your profile (sign up is free), set a date for a live lesson, then 'students' will hopefully flock to see you in action. Its main feature is the presence of a live interactive whiteboard, which you can use when giving live lessons. You can then save your lesson with accompanying materials for later viewing. Test material creation is also possible.

For the 'teachers' it seems to work quite well in that you can offer free or premium lessons, so there is some money making potential for you with WiZiQ. I'm not quite sure, yet, how WiZiQ makes its own money, and as with all edu websites like this, its financial strategy will probably determine whether WiZiQ will flourish or die in the long run. Currently, it is in Beta mode, but has a lot of potential for EFL instruction in particular, although 'students' do need high internet bandwidth capacity for the live streaming.
