A quick help for a newbie

Hey guys,

I just started with the jQuery thing. It doesn't stop amazing me for a few hours now.
However, I cannot get my task done yet and I don't have the time to go through a full tutorial for using jQuery, so I thought someone among you guys can give me a quick solution for my problem this time.

Is there a way I can "fadeTo" from one class to another?
If I have an:
<a>About</a>
and I want a smooth transition to:
<a class="hover">About</a>

What would be the correct approach to do this?

Thanks in advance,
Martin
