 * In WordPress Multi-Site setups where a blog has no users of the role “administrator”
   assigned to it, Subscribe2 (as of version 8.2) will always send e-mail from the
   default e-mail account specified for the blog, and you will be unable to select
   who e-mails should be sent from on the settings page, seeing instead this warning:
 * > Warning: array_merge() [function.array-merge]: Argument #2 is not an array 
   > in /…../ 431
 * Line 431 of class-s2-admin.php reads:
 * `$admins = array_merge($author, $admins);`
 * There should be a sanity-check (has it been intialized to an array?) on $admins,
   as it may be empty in WPMS setups.
 * A solution to this was to explicitly add my network admin account as an administrator
   on the blog in question.

   in the next release.
