Just a reminder/heads up that I would really like to start using this modification, but can only do so when I can grant 'additional usergroups' to use status.
Currently its not possible to do so, because you can only deny a usergroup to use status.
I'll have David send me an ETA for that and i'll get back to you with a quote. As a warning though, we're expensive as a rule when it comes to custom coding.
