Update: It appears that Lone Wolf also sent a C&D to Privateer Press demanding that they police the use of the term Army Builder on their forums.
From the letter
There are two things that need to be done. First of all, improper references to the Army Builder trademark on the forums must be addressed. This can be achieved in either of two ways, or potentially a combination of both, at your discretion. The first option would be to remove such posts. Since this could appear harsh and potentially disrupt forum discussions, an acceptable alternative would be to revise such posts to utilize a generic term (e.g. “roster construction tool”, “list createor”, or “points calculator”) in place of the “Army Builder” name.
The second thing that needs to be addressed is that your forum users must be educated about the term Army Builder being a trademark and only applicable to our brand of products. This is necessary to avoid an ongoing problem and mitigate the future need for removal of improper posts. I’m sure you would also prefer that the forums continue to run smoothly and without interruption, so your assistance in getting forum users to utilize appropriate terms will benefit us all.
