In order to support bots such as the English Wikipedia's [[User:LivingBot]], MassMessage should (probably) have an API module to check a job's status.
No idea what this might look like, to be honest.
This is related to bug 54859.
Neither of these bugs should be considered blockers to deployment, as far as I'm concerned.
Version: unspecified
Severity: enhancement
