I don't mean quality posts or dedicated posters, I mean things like a strong Terms of Service.
Besides a TOS, are there other pieces that are easily overlooked by a first time forum builder?
At the moment, my forum (which isn't live yet) has a "Lounge" for off-topic threads. A FAQ and Newby section where I'll post a TOS (but nothing else at the moment). And one category of on-topic discussions. Is there anything I'm missing (besides more categories and posters)?
You've identified the most common topics - a good TOS (you might link to this with alternate language, like "Forum Rules"), FAQ (could be Forum FAQ (how to post, etc.) and/or Topic FAQ (commonly raised topics).
Other common areas include charters or guidelines for individual forums, and links to "classic" posts. These may not always be read, but they can help guide discussion and avoid some redundant posts.
