it's so nice of you to offer help! We certainly would need help in language services as there will be people from so many countries coming around. It's great you can speak 5 languages. But there maybe problem of your entering the venues unless you are accredited by authority. And the accreditation had been finished before the end of June.
But I really need to improve my English skill for the event:)
Yes, we can share all these things, and they are what I want from a foreign friend:)
