The PMC met an hour ago (see Project Management Committee (PMC) meeting notes - #13 by yanokwa) and has decided to adopt the most recent proposal, but moving the launch date up to next Tuesday, May 29th.
The process for making changes to the website will be through our normal file issue, send in a PR, merge by a committer process at https://github.com/opendatakit/website. The caveat is that @yanokwa and @W_Brunette must both approve review and approve changes before they can go live. Changes that are contentious will require a tie-breaking vote from another member of the PMC.
If you'd like to help with this effort, a number of us will be meeting in #website on the Slack starting tomorrow at 2 pm EDT to help clear up any confusing parts of the site. We'll work asynchronously in that channel until the site is live.
So to summarize, http://staging.opendatakit.org will launch as the ODK website on Tuesday, May 29th at 00:00 UTC (8 pm EDT). If you'd like to help, go to http://slack.opendatakit.org and join the #website channel.
