that's awful. The time left to edit my own comments is absolutely not enough. Why should it be, that 8 minutes after I have written something, I cannot edit my own text? It happened already several times that something turns me away (the colleague asking an urgent question, a phone call etc.) and then I have a text which is incorrect as it is, and I have no power to change it. This should be changed! Each of us must be an owner of his own words.
