Aaah now i see but i do not agree to tick that box... that is the easy way out imho
When i tick this box a whie text input box appears so yes that was what i was missing but.... when i untick it again, i see the original text input box appear for a second and then it dissapears.
This to me means it is a bug and needs to be fixed.
Specially beacuse i editted the text input boxes to my own likings
Ps. It will confuse the members as well when they want to send a PM to someone when they do not see a text input box.
