The result is a 500 error when including a single new group (but grouping is still created), or a duplicate group name error when trying to include more than one (and grouping is not created), probably because they look identical when MailChimp tries to treat it as a string.\r\n\r\nI supposed the solution is to either change the signature of AddListInterestGrouping(), or just creating an array of the \"Name\" attribute of the included groups."}}
