Hey Kristof,
Yes that is a good point! I'll fix this!

Thanks,
Daniel

I just wanted to fix this, but few things came to my mind.

Right now only the user groups that are authorised to post comments, can actually post comments. Is it a good idea to grant post priviligies to moderator groups, no matter if they are selected in the authorised to post comments field?

This can lead to situations where an article is closed for further commenting, but moderators will be able to leave replies there? Is this a situation we want to go into?

no, I wouldn't go that way
one can set who is authorised to post
in our case that is not necessarily the same as who is authorised to moderate

Yes, but what is the point of being moderator if you are not allowed to post?

moderators remove unwanted comments

also, if you want them to post, you can just mark it in the permissions box

Okay this one should fix it:

If moderators are not allowed to post, they also now don't see the reply|quote + edit buttons. They only have publish/delete privileges.

Regards,
Daniel
