OK the problem I have come across is that he needs to be able to edit his threads and or delete them. So he is set as a user in primary groups and a mod in secondary, I then set him as a mod for his forum and edited the mod usergroup to be able to delete own threads and posts. However when I look at his forum View Permissions it seems that he can now delete his own threads from any forum, which is not the access I wanted to grant.
How can I grant a specific user permission to delete threads in a single forum, without giving the same rights elsewhere?
Thanks in advance...
