Hi Marcelo
I think you have completely misunderstood ! As all FabLabs inside universities Fablab SP has an appointment by e-mail for using the FabLab in the open day , that is on wednesday !
And as a great University , USP has many employees and many of them may not know exactly the functions and rules of the FabLab.
As you may not know, this FabLab is the first from Brazil , and from there many researchers and fabbers has being formed !
Also there is the CNPQ researcher group DigiFab that makes research in this area there.
There are many social projects and activities !
I personally have developed several projects there exactly in the open days and in the research group !
What seems so strange to me , is that you register here exactly in the day you make this comment , and not only here but also in other discussion group!
What are your interest in saying that?
All the best
