In the world of Hai:
A few quick fixes today, thanks to suggestions from @Alan:

  1. The "Leave Room" button on rooms has been moved to the upper-right corner of the page, where folks are less likely to click it accidentally.
  2. In the compose pane, the Public, Comments, and Editable checkboxes should now stay with their labels if they have to wrap down to the next line.

There was also a bug causing @'s to display incorrectly in preview (they worked fine when posted); I've fixed that as well.
