A BOF is an informal meeting between developers and users with no outline in which anyone can ask any question he is interested in. They are quite enlightening because developers get the chance to know what people think and people get to answer the questions they have. Consider with the administration how many tables and chairs are required at the booth. Please ensure that there will be enough power splitters at the booth so the will machines actually be able to be turned on. Bare tables don't look nice, you may want to consider using white table cloths so the whole booth will look more professional.
Some events organize a social event for speakers and exhibitors.
Please ensure to take enough fingerprints of your GnuPG key with you so others can sign it. Please also don't forget a passport or drivers license to prove your identity. Mails covering organization of the booth and talks should be sent to one of the mailing lists so they get publically recognized, archived and can attract more interested people to attend. We won't step in contacting the administration bypassing your effort though. If you want to run a professional booth, it is always good to know where to put jackets, superflous shoes, drinks and other stuff.
