I just can not figure how to do that
I want users with more than 200 posts to be the only ones that can post on one of my forums.

Rick explained it as:


I think i need it translated to the version for dummies...

You make a group that has permissions to the forum.
Then in the group there is a field to set how many posts to auto join the group called post count.
Control Panel » Group Management
It is only editable if it is a not stock group.
In fact at the bottom of that screen it states
"By filling in the Post Count field you can make it so users will automatically be added to that particular group once they reach the designated Post Count. Leave blank, or 0, to disable this feature. "

You mean I make a group with permission just for that forum and set it to whatever post count I want?

Then i can have several groups with various posts count requirements?

If i set it to 100 then the people that can see that forum are not removed from the other groups... they are just other to this one?

Right.
First thing is to add a group say called 100 club .Set the post count to what you want 100.
The goto the forum permissions and set the permissions to post and reply to allow only 100 club. Or for that matter you can completely hide the forum from any group you want
When a member reaches 100 posts that member will be added to 100 club automatically and still be in whatever groups they were in to begin with.
So whatever permissions 100 club has they will be upgraded per say.
You could do a lot of things like allow bigger attachment sizes add other permissions they did not have etc.

Then you can do the same for say 200 club

BTW you could also tie this in with member titles.
Control Panel » Profile Settings
It has a post count setting also

Thank you
I have the new user group working... set it to 100 instead of 200 but that is irrelevant
And it seems to be working fine except for the fact that two users with more posts than needed have already ocntacted me to ask why they can not post
It looks like many users with the correct number of post have been added to the new group... but most were not...

Are there some users, like merged users, users in other groups, or similar that do not get added? Can not find the logoc as to why some were added and some not...

Check what groups they are in from the control panel to make sure they are not in a special group with different rights that may not allow them to post. Other than that they may just be stuck for other reasons so while you are viewing the user just manually add them to the group and see if that resolves the issue. If not then back to my first comment. They may be in another group such as moderators and they are not allowed to post in the forum.

i can add them manually without any problem

Could it be that i changed the settings and the number of posts required a few times?

what if i changed from 500 posts to 100 posts? will all permissions be reset or not?

Possibly,maybe they crossed the threshold while you were making the changes.
Just goto member management and check the box next to the group in question.
You could test at the same time by using the become member button.
If the member is online while you become the member they will be bummped off while you are logged on as them.

i am talking thousands of users not being added and not a few... and they all seem to have the right permissions and nothing unusual with their accounts...

How long does a new group with post restriction take to populate? I created a new one to test... set it to 200... and it show zero users... should it not show all the users with more htna 200 posts?
