The free version provides all CortexPlatform features, including the CortexDB, CortexUniplex and the APIs (UniplexAPI, JSAPI).
You download the new version from our website and update your server.
Community-based support can be found at our github projects and you can write us an email. Or you start the first thread in Stack overflow ;-)
Users should be directed to download their own copy of the CortexPlatform from our download page.
You can, but the number of users are limited and the passwords are not changeable. It makes more sense to get a fill licensed version of the CortexPlatform.
We encourage you to share your work publicly (e.g. on github) and link to our website or our github projects.
