Thanks, so these are objective, known numbers... > Since our registration ison your reasoning for still open, we can estimate > 350-400 > people where 75% of people (262-300) requested accommodation. .. but it is still unclear on your reasoning for your 350-400 estimation. Is it based on something like registration "timelines" seen at previous DebConfs, or...? Obviously we don't know the number and nobody is going to hold you to it (!) but given that it meaningfully affects the entire budget, we surely just can't just be guessing at it or at least we should be explicit that we are doing that. We certainly should not be adding any component of wishful thinking — simply adding people to this number won't make people magically turn up. (Again the idea is to identify any potential risks in advance so that we can plan for them, rather than any comment on your advertising or organisational skills!) > However this list of budget overestimated the attendees paid by > themselves (45% of attendees were used in estimation).

I've spoken to a number of people who have held t-shirts and other related merchandise for Debian in the past (and have since stopped). They would warn you that are overestimating or trivialising the burdens of managing and storing such an inventory. This will be compounded here by the t-shirts being event/date/year specific and, given you concede they will be rejected sizes, you will likely have an unrepresentative distribution of "sized" stock too thus making it harder to shift later. > > > Also, NCHC (National Center of High-performance Computing) and III > > > (Institute for Information Industry) funds are not yet included.

I'm afraid I don't understand the arrangement. Using informal language here, we can spend money on DC18 and ask them for it? (What are the limits?)
