Oh for goodness sake.

Spamming the list, _and_ individual developers every day is not the way 
to get an answer to your question. Now we're all just pissed off and 
less likely to answer.

If we're not answering it's because we don't know the answer, or your 
question isn't clear. Probably both.

And please don't send me private mail looking for answers to questions 
which should be asked on this list.

I suggest you go away and think about your problem and try and solve it 
yourself before you pester us any further.
