Sorry... I've been busy, read lazy...
Yeah... The comments need to be approved by the moderators so that you will be able to see it... I don't believe an author can moderate the comment by themselves... Not sure if such functionality is built in though...
We need to moderate the comments first hand due to the amount of the spams we get through the comments... It's gotten down quite a bit now, but I still get to delete alot of spams...
I guess the notification flow in the CMS do not quite correct... If somebody posts a comment, it goes to the moderation queue, where a notification email to a moderator would be nice but missing, and we approve/disapprove them... and if we do approve them, the CMS should notify the author so that they know somebody added the comments... But it seems it is working sorta backward...
