This is the document we use to plan for the costs.
The way it works is that every local event organiser leaves a comment below containing the list of resources for their event, and estimated costs of each. This enables us to collectively keep an eye on the overall budget so that we can discuss and then and then upload into the collaborative budgeting before you spend any money.
Then @MariaEuler @marina and myself go through the budget document, do some admin adjustment of budget posts and explain the process for how to upload the proof of expenses in order to be reimbursed for them. If you have any questions please do not hesitate to post them in a comment below…
