Hello, the contributors will be edited afterwards I find so far very ok, if these are errors etc. However, if a corresponding comment is completely changed by the user and the meaning falsified, if it has already been answered. I am therefore for this that one can edit a contribution only as long as there are no new answers yet. Finally, some comments refer to an occurrenceal tar. However, if this is completely changed in the sense od it is only replaced by a “Christmas greeting” so the mM is not i.o. In affected case and with users it is known that that very gladly do this I only write in the quote. However, I find that is not the case and should be stopped.
