Right, don’t worry, I’ve figured it out, well, when I say figured it out what I really mean is I’ve figured out the correct question to ask google.
So, if you’re having the same issue, go to the plugins section of the admin console and search for a plugin called ‘Category Posts Widget’, then, once it’s downloaded, installed and you’ve activated it, go to appearance (in the admin console), widgets and hey presto there’s a new wdiget!!
Drag it over to the sidebar on the right and configure it by telling it which category it should show.
Then, drag a new one over to the sidebar and select another category..
Amazing!!
Njoy.
