Wait for flash demo to load.  If you can see and hear it (excuse the hiss in the recording) then most likely, your computer system will allow you to attend online help sessions for teachers and tutors. To attend,  join WiZiQ (membership is free) and then use this  first contact form   to provide the site author with your email address. 

Invitations will come in the form of a WiZiQ URL via email. The email sent via  WiZiQ will provide meeting times in your local zone - the one you specify in your WiZiQ account.  

Tip A: During online meeting, if you do not listen with a headset, you may have to mute your speakers when you speak.

Tip B: I use a Genius mouse-pen tablet  for on screen drawing.  It took time to identify a good combination, and a good location for it.
