Have you ever posted a comment on Facebook only to regret what you just posted? Well, up until now, all you could do was delete the comment and repost it, as FB didn't allow editing it later. However, that is a thing of the past now, as you can now edit comments on the social networking website.
Once edited, the posted comment bears an "Edited" tag. You can also check out revisions as the service also shows editing history for a comment. This feature allows people who have commented or liked the main post to view the conversation in its full context. Check out the gallery below to figure out how this feature works.
