Forum OpenACS Development: Re: Re: OpenACS Permissions System - Performance Improvement Work
In fact any one post, regardless of whether a particular post is well or poorly formatted, must never break the display or formatting of all the other posts in a thread.
IMO this is an important correctness and usability criteria, the sort of thing that OpenACS is usually good about getting right, and much more important than getting the particular background color or whatever that someone prefers. But people making look and feel changes to OpenACS appear to sometimes completely ignore all such UI correctness concerns, and repeatedly re-introduce this bug. I'd say that's rather embarassing to the project.
If a user mis-formats a post, it would be very nice to have any easy way for a Forums admin (or better yet, any one of many trusted and designated "power users" or "sub-admins" in the community) to fix that one post. But that's a separate issue.
