WordPress Demo Staging Section

Hi,

I am running WordPress 2.8.4 on PHP/MYSQL Linux based hosting.

I am working on various customer projects implementing their websites into WordPress format. We have done the initial implementation of the websites and went live with them.

However, I need to find a way to have a demo / staging area for each website where I can check out the updates required by the customer before going live. Our usual workflow is that we update customer website content on a demo section before uploading live as the customer requires proofing/spot-checking the content before going live with any content.

Any help would be greatly appreciated

Thanks

Deepak
