Is there a way to export a website built in VSD off site so someone else can review it before posting to the web?

If i understand the question correctly, if you have an external usb type hard drive, i think you can download a copy of the VSD program onto it from CC account, and then copy your folder from your pc to the external drive as well, so another pc laptop etc can run it on the hard drive, also should then be able to edit it as well, and return to your pc afterwards.

However would be adviseable to have identical paths etc for everything so i would do a save as of your whole project to desctop, and copy that accross, so you can then re open it from the hard drive and check everything works before you jump in the car, and get to your client, to just to find all the images or flash files have gone missing.

This is where an SDrive account comes in handy.
I put live samples on one of my SDrive spaces then send a link to the client. It's very easy to make changes or adjustments, then take the site/page down when it's ready to be uploaded to its permanent home.

You could do the same thing on any website (use a sub-domain), but it's so fast and easy on SDrive

Thanks for your input
