Checkbox "Mailversand aktivieren" shouldn't change text if marked
Description
When creating a thread, there is a checkbox “Mailversand aktivieren”. When clicked, this changes the text to “Mailversand deaktivieren”. This is very confusing for users because they don't know whether “Mailversand deaktivieren” has been clicked or something else.
Goal
Simpler understanding of the checkbox.
Solution
The text should not change.
