Hi,
I want to add the case team related list to the page layout for my community members but, with that comes a button where the community members can update those on the case team.  While I'd like my clients to be able to see who else is copied on a case, I do not want them to have access to update the case team.  Salesforce Support tells me that because the list is not customizable, I cannot remove that button.  They suggested I post my question here.  Anyone have any ideas?  Or workarounds?  
Thanks,
Dana

Here is the code on the custom "New" button:
https://vitl.my.salesforce.com/02i/e?retURL=%00bd0000000j1wB&acc_id={!Account.Id}&Name="Do Not Edit - will auto populate"

Here is the error message the user receives if they then select the "Cancel" button:
