Just to keep you posted: everyone crossing limps / toes / fingers /eyes or whatever for me : you can uncross now. And many thanks for your crossing support.
I did get the job - alas, it didn't quite turn out the way described. Instead of a contract for several weeks it's only a 20-hour deal (not 20 hrs / week but just 20 hrs). But, beggars can't be choosers and I will do my best to impress them enough so they hopefully call be back or even better, keep me.
Now I just have to get hold of them so they can actually explain to me what they want
