Am just in touch with CKSource (vendor of CKEditor) to get the license for Extended Support for our xWiki instance.
Would anybody from xWiki community be open to work on the provision of CKEditor4 ES module in the xWiki as an Extension?
There is requirement to buy a license to make it work.
CKSource is open for discussion and provide the support to the community.
Once agreed on purchase of the license for our xWiki, we would be open to share our experience.
