Q: I want to put something on the internet, but how do I do that.

A: I want to introduce you to the digital representation of a sticky wall - a drag-and-drop interface - Padlet: http://padlet.com/ (in case you didn't know about it).

It is available in Chrome browser. If you consider using more interactive tools with your students online it is a good addition to a blog. It gives your students more control on building a group website.
