I'm sorry for my previous response... a 
monday-morning-bad-temper-leave-me-alone one that was very 
non-constructive. On top of that it is quite stupid to ask for help and 
at the same time claim "you'll have to take my word on it".

Please accept my apologies.

Of course. My monday-morning bad temper is over by now, and I hope I 
didn't transfer it to any of you. I'll provide the panic, one way or 

Again, I apologize,
