Hi Juergen (dang US keyboards with no umlaut!),
Fair point. But these writing requirements are for 15 YOs. I think most of the people on this site have probably passed that age.
I don't think we are expecting perfect spelling or perfect grammar - just that the OP attempt to fully formulate what exactly it is they are trying to ask - to put as much effort into the question as they hope they will get in return?
On another note, I have found very often that just thinking about writing a good question will provide me with a 'fresh set of eyes' and it helps me find the answer myself.
But then again, I don't ask people to google stuff for me either. :-)
