Congratulations, Roberto, for achieving 5000 posts!
Considering the small footprint of this forum this is truly unique ;-)
And while 5000 is an impressive number, your kindness, patience, and your contribution's quality are even more impressive, numbers can't tell the whole story.
It's no exaggeration to say that your contributions belong to the most helpful ones - without them this forum wouldn't be as useful by far, NI (and we all) should confer a decoration on you :-)
So thanks a lot for sharing your time and knowledge!
