I know there is "Paste Text" button in CKEditor, and I can limit allowed HTML tags.
But it's very hard to explain clients to use specific button when they insert text.
As result they often insert "dirt" texts with HTML tags.
As I remember there was setting in early versions of CKEditor to force insert plain text by default but cannot find it in current version.
Is there any solution for the problem?
UPDATE: I don't want to restrict user to use some tags. But user should get "clean" plain text without HTML tags when insert text.
