Hello, I think that MassMessage should automatically use signature, date and time for DiscussionTools. When is there no signature, date and time, it is not possible to reply using Reply Tool (the part of DiscussionTools). It is a pity when I cannot reply to a message posted by MassMasage. This should be a big problem when Reply Tool will be available at all Wikimedia project.
