I'm seeing the following error message:
Notice: Undefined index: settings in commons_notify_commons_utility_links_alter() (line 163 of commons_notify.module).
As far as I can see, Commons Notify expects Commons Follow UI to execute via drupal_alter() first and pass through the $links['settings'] key/value pair. I don't see why this is necessary and will post a patch that eliminates this assumption.
Seems to have coincided with installing Modules Weight?
