The short answer is "No". From the Rules on Posting section of the DSLReports site FAQ:

"No user of the site has any right to post anything they feel like posting. If a user posts, they have to live with any editing or deletion or other moderator action without public complaint."

In addition, each forum has it's own posting rules and guidelines. The DSLReports Efficient Forum Rules are available via the "Please read the Forum Rules before posting." link at the top of the forum.
