i've made the document i/we used for planning the Mountain States BikeBike! in 2010 publicly viewable. it's a multi-page spreadsheet. it's become my go-to document for planning an event, class, or other involved project, especially ones that will be collaborative in nature.
as is usually the case with this template, some of the pages got more use than others, some were sort of abandoned mid-project (based on little or no use) and i've removed the data like personal contact info, names, etc, to protect privacy, but you should still be able to get an idea of how it works. feel free to share or use or improve this. i've not looked at it in at least two years. if you have any questions about it, feel free to ask.
this was done well before we had an active social media presence. i'm positive that if i were updating this document, i would include a page for keeping track of things like facebook event creation, tweet schedule, and any other social advertising ideas.
