this is for an elementary school situation where they're considering using blogging as part of the curiculum... but they're concerned about abuse. What they'd like to be able to do is try and filter any comments/posts with questionable content. I think the easiest way for them to do/manage something like that is to have comments that need to be verified moved to a moderators queue, with the posters details recorded. Even better if it can be plugged into/or somehow use another tool such as Dan's guardian as the filter (I've heard it does a reasonable job of phrase filtering.) Obviously this is just a helper, and not a cure- teachers would still need to be involved (perhaps an RSS feed of all new posts?)
I have no idea if this is even feasable with WordPress, but WordPress comes highly-recommended, and I'd like to suggest this as a potentially better alternative than Movable Type, which is their current first choice.
Many thanks in advance for any help the community can provide!!
