I search for 2 Modidications.
 

1. Points system :
This mod adds Rating Points to users as they post in your board. It displays these points next to a user's post.
Example: "Rating Points: 534"

The rating point stats are displayed on posts and the users profile.
(users can move thier points to another users, admin can manage this option).
2. Hide / Lockdown
This mod creates a [hide] ibb code that will
show the text in between the tags only when the
user has posted in that forum after the post
with the tags. Guests can not see the hidden
text at all.
(if it possible - Admins will view the text without to posted an reply).

Thanks,
Ori.
