Lock editor font color under different circumstances

[Ting]

I want to lock the changing-color function of editor under different conditions. 
For instance, when UserA logs in, the font color is black, UserB green, and UserC blue.
They cannot change the font color. And UserA is able to add new words to the phrases UserB typed previously (not changing but adding).

Please let me know how I can achieve this goal.

Thanks.

Hi Ting,

Thank you for considering Kendo UI.

Unfortunately, the desired behavior is not supported by the Kendo UI Editor out-of-the-box. In general, collaborative editing is not available at this time. Sorry about that.
