If OP where using these images in a negative light i can see why there would be an issue.
But the fact remains it's a positive use of their logos and images on a website in which they are already featured, and as such i don't see any issues.
RHS:Escalation is a publicly released mod (or will be), we can see the time frame will be tight but Zeus missions are not hard to create and by what I see the framework of alpha stage is there he just needs to put the units down on map and be done with it. He has credited on the MANW thread RHS link both in description and third party content HYPERLINKS to their MANW page, thus diverting web traffic to their page too.
I see no issue with tmortensen attempting, in a strict time frame, mission to MANW using third party content in which is credited.
So what's the issue ?
