If I am trying to permanently disable a workflow (but it’s locked and from a third party bundle) what is the best status to set it to? Testing, Suspended, or Not Initiating?

Not initiating. Testing means it will still run under the (creator/admin), and suspended stops it in its tracks wherever it might be in the process.

thanks! i really don’t use workflows much, and the statuses were a bit of a mystery to me. but in this instance, I have about 40 of them I have to “shut-off”, without actually being able to get rid of them.
