Still nothing back from them. I gave them two chances to find any problems after I made my final changes and they've not complained, so we can now take that as us being in the clear with everything we'd done to that date.
The ironic thing after all of this is that Rob's comment about how we "will see a profound decrease in your Google search results over the next week or two" has kinda backfired. Despite the fact that we now only use Army Builder to reference their application and never as the descriptive noun and verb for an application to create army rosters, we've now moved up from between 8th and 10th to 6th when I search "
army builder"
All perfectly above board, but definitely showing that you can't shoot down the competition that easily on Google
[edit] Also, it appears that Rob has
openly admitted that there is a difference between
infringing ("Fred's Army Builder", for example) and
improper use (such as a user asking for "an army builder tool"). The former they have to threaten over, the latter they just have to try to educate. That's not to say that I advocate improper use (given the threats of legal action, I'll probably have to keep this site clean anyway) but it does appear it isn't actionable in and of itself.
