Suggest adding the name of the logo before every message sent from the add-on. Something like "{rt2} CrossGalbming : " - that would add a coin and the name of the add-on.

I get most people can tell the difference, but you always get that one guy, "Why did you say that?"

Plus, it's good branding to help promote the add-on.
