One key item that came up during the summit this week is the need to effectively reach people with important announcements.
Currently ODK has an #announcements category here in the forums. In another project I worked on, we had a Discourse group like this with restricted post access. We also set up every Discourse user to "Watch" the category automatically, so they'd receive email notifications for every new topic.
This could also be combined with the WordPress Discourse plugin, if the odk.org site continued to run WP, which could "echo" selected blog posts as new topics. The plugin also optionally allows the blog post's comments displayed on the WordPress page to be replaced by replies to that associated Discourse topic.
This could allow a few ways for people to track "announcements". Do others have alternative ideas or experience?
