H1: About 1st&2nd classes of Winter CM

I've already downloaded zotero in last term's CM course but I didn't know how to use it and how it is useful actually. Now I realize zotero will help me to write essays and I probably (hopefully) won't have to stay up all the night to make the works cited any more. How great zotero is!

And I knew I can upgrade the Firefox portable changing any settings.
