I can't access the boards even though the admin approved it. 

How do I reduce the size of all of the icons?

Looks like you have your browser's zoom setting turned all the way up :)

Either click the little magnifying glass in the address bar, or hold down the Control key and hit Minus (-) a few times, to zoom back out.
