User blog:MrBismark/How to edit templates?

How do you edit template boxes like this? I clicked on the VE thing but can't change anything. Is it even possible to edit?

Also I am using the blogs to ask so that more people can see it and it takes less time that going up to an individual and putting something on their message wall and waiting for them to respond or for another person to see it. Real shame I have to explain this, shows how we live with China-style authoriatarianism.
