I see the option
submitter bugnumber originator-address | !
Changes the originator of #bugnumber to originator-address.
If you wish to become the new originator of the report you can use the ! shorthand or specify your own email address.
Is this my only option? Is there anything else I can do? If not, would I just email control@bugs.debian.org the following?
submitter [lots of bug numbers] new address
Also, does this submitter command work with closed bugs?
