og + userpoints + user badges

Hi,

How to configure Organic groups to work with User Points so that Group owner assigns user points to user of that group based on post, comments etc.

bascially a taxonomy should be assigned to a group and when a user posts a content in a group points should be assigned to that user pointing to the group taxonomy.

i e each group owner should have a control over the User Points and the group taxonomy

any help.....?
