Yay, I've finally worked out how to do it! I've tried reading instructions and following videos to work out how to create a link in comments back to my blog but couldn't quite understand how to do it - all those letters and symbols just confuse me! SO.... I googled html link code and found this generator.
All I had to do was type in the text I want others to see (Down Under Teacher) and the link address (this blog) and it did it for me.
As my one of my little year 2s said when we had questions about insects last term - "Just Google It"
