Site Cloning

I am kind of a newbie to IM but have talked to a few guys who do a little site cloning. Can someone help shed some light on this for me. It seems very interesting and something that I am seriously considering if it isn't too difficult.

You will find a lot of info in this forum on that topic. Just do a search. I clone a lot of sites and I use a plugin that wipes out all the posts, tags, etc.. and I can start new which cuts down on a lot of time. As long as I have all the content I can get a site up and starting to promote it in no time.
