The new CorelDRAW Conceptshare that comes with the new CorelDRAW Graphic Suite X4, is a great addition to the suite. And will be a very helpful addition to ones work with clients and co-workers. As a freelancing illustrator & artist I have already been using it, and its been working just fine. What one do is to upload once project, for example an image. And then "Invite" a client or co-worker, to log in on the online site, to comment and suggest, by writing on a notpad, draw with a pen, chatt and so on. Making it very easy to quickly comment on a on-going project. See the image. You can comment and make mark-ups while you all are online at the same time.

For those of us using CorelDRAW Graphic Suite X4 (CorelDRAW X4 and Corel Photo-Paint X4), we can easy connect to our conceptshare workspace/account, either via the Conceptshare docker, or via File>Publish to Conceptshare.
Try it out. There is a free account one could try out. For company´s or others with more than 2 projects at the same time, with heavy weight files, there are payed accounts with even more encrypted accounts, for those who need it. Here is a another very simple idea of how its working.
