Many people find that they have left a glaring typo or mistake in a comment on someone's Facebook status update.
Facebook knows that, and so has now introduced the ability to edit comments on the site.
According to reports, this tool will be available to all Facebook's 900m+ members over the next couple of days.
The new editing option, long called for by the site's users, only applies to comments, rather than status updates.
Facebook started allowing people to edit their comments around a year ago, but gave them a 30-second time limit to make the changes.
Now the time limit has been lifted, meaning users can go back at their leisure to previous posts where they have made an error, and then change it.
However, Facebook will also display an Edit History for each comment in order for people to see the full history of the conversation.
This means that people cannot use the feature to just go back and change a potentially controversial post they had made on the site without potentially getting found out.
TechCrunch has reported that the editing system will not be introduced on the embeddable Facebook comments system.
However, it is hoped that Facebook will soon transfer the feature, as Facebook comments are used by various websites and online publishers.
