Greetings!!! This is a Master student who wanna attend the IETF 54th meeting in Yokohama. I would like to make some contributions to this meeting. But I could not find the information on where I should contact to volunteer to support the meeting. I have been experienced in not only video conferencing tools like MBone tools(Vic, rat, etc.) and H.323 tools but also digital video broadcasting applications like Realnetwork video, Cisco IP/TV and so on. So I could help in setting up and engineering video streaming system or network cabling for the meeting. And also, I can help selling T-shirts, distributing brochures at the registration desk. :) Could you please let me know the appropriate contact point to those things at the 54th IETF meeting? I'm sorry if this list is not an appropriate place for this question. Thanks in advance. Regards, Joonbock Lee
