The ability to edits comments can be useful but can also be confusing if users abuse or misuse it. It should be for a forgotten item or a typo but if a user keeps editing a comment, that may require others to backtrack to figure out what crucial information may have been changed.

Please add a configurable time window (e.g. 15 minutes) after the initial comment was posted during which the user can edit can still edit their own comment but not after.
