I don't know if this is the appropriate exchange site for this question, but here it goes:
http://ckfinder.com/ has 3 licenses.
I would like to incorporate this software into my existing CMS, but am a little confused as to whether I need the OEM license, or the Corporate license: http://ckfinder.com/purchase
I typically use this CMS for third party clients who request a content management system for a their pre-existing sites. Any help would be appreciated!
