Hey, thanks for the reminder and bump on this thread.
I appreciate Enzo's point about consent and information sharing, but at the same time I think Bike!Bike! organizers have a responsibility to be transparent and accountable to the community, and the financials should be accessible, along with other useful documents that could help anyone interested to understand how these events are organized (including problems and roadblocks that some orgs face in the process).
Perhaps we can work towards a standard of how this information and documents can be shared and accessible moving forward, including certain information that should be accessible to future hosts.
I will say that we hosted so long ago in Toronto that the numbers are laughable (I think we spent a total of like $2,000, including $1,000 on food?) but I will look for our budget from hosting the regional conference in 2019.
In regards to breakdown for committees, you're pretty much spot on but you may want to have another group for communications. While each registration element will likely need a main comms person (housing, workshop organizing, bike lending), you may want someone who is bottomlining your outreach, invitations, website copy, welcome package content including a map, + translation elements. This may include a web-person, or you may need a whole web/mobile team, especially if a lot of the comms stuff is going digital and we will be livestreaming workshops etc. ....
My 2-cents :)
Ainsley.
