Hello Herlia, It is great to see you join classroom 2.0 One of the great advantages of using web2.0 is that the tools are free but good internet access is usually necessary. Dont be afraid to ask for help from us when you need it. Enjoy your IWBs - I often wish that I had one.
With your interest in Education Technology, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service.
