Where do I edit that?
Like 20 posts - 2 stars
40 posts - 3 stars, etc
And how do I make that they automatically get a text udner their name with the stars?
ACP -> Users & Groups -> Groups
Create separate groups, and through group promotions settings, make users move from one group to another upon post count as you mentioned.
Now edit each group and under "User Stars" option, set the number to 2,3... as per the group.
I can't seem to find the options you mentioned.
I created a new group and then this:
General
Forums and Posts
Users and Permissions
Miscellaneous
I can select the options from there.
I don't see anything from making users move...
In that "General" option, set the number of stars. Then save those groups.
Once you saved them, find "Group Promotions" setting, in the left sidebar below "Mass Mail".
Select "Add New Promotion".
1) Give it any title and description (it can be anything).
2) Under "promotion Requirements" select "Post Count".
3) Under "Post Count", enter 20, 30 or anything you wish. And leave the option "Greater Than", as it is.
4) under "Original Usergroup" select "Registered".
5) Under "New Usergroup", select your new usergroup.
6) Leave other options as such, and press save.
I found it. Thanks for your trouble.
