Why can't I edit the details of my artifact?
Only artifacts with a verification status of Unverified can be edited from a members repository.
Once a verification request has been made the artifact details are locked. This locking process ensures that the artifact details reviewed by a Verifier don't change.
The following screenshot displays the Artifact Details window for a artifact with a Pending verification status. The member is informed that they will need to remove the verification request if they wish to edit the artifact details:

If a Pending verification request is removed then the Verifier will receive an email informing them that their verification is no longer required.
