"Brand Guide" information on recommended usage of the Grunt logo

I hate to ask this, but it seems to be a reality in corporate environments that this needs to be asked.

The Grunt web site needs to have an explicit statement about whether the Grunt logo can be used, and under what limitations, if any.

I'm publishing some internal training presentations in my enterprise, and I have a feeling I'm going to be forced to remove the Grunt logo from all of them, unless I can convince the legal team that this is reasonable. Without a legal statement addressing the ability to reuse the logo, I'm relatively certain they're going to tell me to remove it.
