Hallo Mathias,
This is Ale, from Wikimedia Brasil.
I hope you had time to recover after being kept in the USA and will be able to make it to
the event in São Paulo next week!
In case you do come, please feel welcome to contact us through our mailing list:
wikimediabr-l(a)lists.wikimedia.org
Plus, though you'll probably be well attended by the event staff and organizers, if
there's anything we can help you with, dont' hesitate.
Have a safe trip, und auf Wiedersehen
ale
