Registered Disqus users can edit their own comments by clicking the Edit link within 7 days after posting. After 7 days, editing is permanently disabled. Disqus does this to help make comments less susceptible to spam abuse.

Guest commenters should contact the moderator of the website where their comment was originally posted to request that it be edited. Editing is also disabled for moderators for comments older than 7 days.  It's up to each site how they manage their discussions, including how to respond to commenter requests.

Comments made with a site-specific profile can only be edited on the original page where they were posted. Comments made by site-specific profiles cannot be edited in Disqus Home.
