Hi Jonathan,

and first thanks for your work!

I'm currently traveling, therefore it will take me a couple of days to 
get to the actual patch, sorry.

In the meanwhile, just to be sure, is your new assignment on file? 
Probably the answer is "obviously yes" and I just missed the relevant 
message...

Thanks,
Paolo.
