I have successfully linked my pdf file of Skype instructions to my social network page. I have finished checking all of my site now including my references and hopefully everything is as it should be.
On reflection, I have found this unit to be the most effective learning tool to date. I have contributed to and participated in  the discussion board, posting questions and asking for help, (for example how do I reference a screenshot) and have been surprised by the response of help I've received from other students and the support I've received from Jenni.  I have learnt to create a website which at the beginning of this unit had me worried as this is something my minimal computer skills have never attempted before using software unfamiliar to me some of which I'd never heard of !  I've surprised myself and my family at how much I've learnt albeit at a slow pace!!  I have reaffirmed my belief that you can be a 'life long learner'.
