Just a little bit info about this.
On International Clans (HC) only the group of the clan have permission to make topic and reply on topic on their forum clan. The other groups cant make new topic nor reply, they can only read the topic.
For example |dZp| Yeoldegod made few topics in general. Only who are in |dZp| group have permission to reply and make new topic on |dZp| forum while other groups can't, just read it. Also they can't make topic nor reply to other forum clan, they can only read it.
Administrators have permission to all!
