Yes the topic starter has the right or the ability to delete his own topic. Unfortunality this will also delete all the valuable answers of other SZ members. I absolutely agree with Scottyee in that point.
I spended so much time with reading this thread, understanding the different opinions (in my special case I had to translate it into german at first) and building some well formatted sentences including my own opinions.
And then, with one click, it's all gone. This makes me feeling like I'm wasting my time...and that makes me sad...

Thank you, Scottyee, for saving the thread!!!
