First off all set down clear guidlines which you can always come back to when defending your disition, always come back to these when members ask why they have been banned, what I have found usefull is what we call a trafic lights system, they get three warnings then their banned for ever or an ammount of time depending on the reason for banning. For less serious behaviour on the forum for example members making duplicate accounts, etc, putting in place certain restrictions on the content and features they can get from your community is good. However it is important that you dont give into these people and that you set an example to all of them. Maybe you could have a banned list open to the public showing who's banned this can be humilating for the banned user who may not wish for their 'name' to appear on that list again. I hope these suggestions are helpfull.

Thanks,

1 thing that I love most about some forum softwares is that you can give them an User Infractions & Post Reporting Options

If your staff is not respectful to a superior. I think the best things you do is to talk to them one on one and not warn them. But tell it in a friendly way that does not hurt their feeling. Act as professional and as a friend.
