You want to contact list owners
When you have a question or remark about a specific list, the address you should write to is: nameofthelist-request@listsdev.hbs.edu (replace 'nameofthelist' by the name of the list).
If you fail to receive a reply from a list owner (they may be busy or away), open a ServiceNow ticket to TSS about your issue. Please describe the problem and include the full address of the relevant list. Example: "I can't post to trees@lists.hbs.edu and I think I should be able to".
