In general you may not edit or delete your proposal after it has left
    the Proposal stage. In urgent cases you can contact the PEAR
    community via the developers mailing list to
    reach a PEAR website administrator to do a change. This is heavily
    discouraged however! You should have made everything clear to the
    community during the Proposal stage to ensure a hassle free voting
    process. Even if the voting has a negative result, this is no reason
    to delete it.
