I've run a relatively small forum-based gaming community but it's growing and starting to get too much for one person to handle, so I'm looking to add 2 or 3 moderators to help me out. It's mostly just helping newbies learn the ropes, and reminding some of the older members of the rules too. There's the occasional troll that needs dealing with but we're pretty lucky in that most people are there because they are interested in being a part of the community.
We use PHPBB so it has some pre-set moderator tools, but they seem to be pretty in-depth and offer the ability to modify other peoples posts and things like that. I'm not sure if I'm comfortable letting people modify other peoples posts. Is this normal for a community? I can see how it's useful for Stack Exchange, but for a forum where people are posting their points of view in a discussion rather than it being a resource I'm not so sure.
How do you determine what level of access and powers to give moderators when you're starting with your first moderators?
