I think it's an example of why it would be useful to be able to edit one's postings. Not only to correct unintentional errors and errors discovered after the fact, and to fix broken links, but to rephrase or remove inflamatory verbiage and statements prone to misinterpretation. Rather than avoiding responsibility, I view it as helping to improve the overall tone of the site and the quality of the information. If really needed, Mudcat could provide the ability to view a thread with posts in both edited and original form, reconstituting user-deleted posts. That would address the "responsibility" issue.
