Sorry for the confusion...
The real question is in the first message, the second one does not make any sense
I wish I could delete the second one

Oh boy, computers have a mind of their own...

Yesterday evening I sent a first message which went away unfinished thanks to hitting the wrong key too soon...
Then I realized it and sent a second message with the complete question
For some reason, the second message was published first!!!
So the second published one did not make any sense, sorry about that

Is there a way for the author to delete his/her message when needed?
