A big hello to everyone here, this is my first post!!

I'm really new into this sort of thing, I've mixed my own tracks before, but after stumbling upon this site and hearing some tracks, I became very interested in making my own remixes....
I was just wondering how I go about it, I've read a dew this on this board, but I've become no clearer on it.
I've got Cubase, Reason (with which I'm still very much a beginner using) and I have ACID Pro, which I can use quite competently.
Are there any tips or can anyone help me get started....
Cheers
Paul!
