You can download a free trial version of the BlueBridge Wiki Extensions for Microsoft SharePoint here:
Simply unzip the file and run the installation wizard (setup.exe) on the server.
With the free trial version, you can test the BlueBridge Wiki Extensions for Microsoft SharePoint for 30 days with all of its functionality.
If you purchase a licence at a later date, we will send you a new licence file to be used on your server. Once your trial is complete, you will no longer be able to use the advanced features that the Wiki Extensions offer (e.g. PDF Export, lightboxes and tables of contents), but you will still be read and edit wiki articles as in a SharePoint standard wiki.
To help you get off to a good start, we recommend downloading our knowledge base template for Microsoft SharePoint 2010. This free template creates a site collection that already includes content, meaning you can see the BlueBridge Wiki Extensions for Microsoft SharePoint in action and test them more effectively on your own servers.
You'll find a quick start guide in the ZIP file to help you deploy and work with the template.
