I wouldn't worry about the other site. You should have more to worry about from Lucasfilm or Firaxis, if you are truly worried about copyrights here. If it were only a matter of using the name Vanguard, you would have nothing to worry about. No one would confuse Basketcase's project here on CF for that drivel in the link. Don't worry about it. His copyright is there to protect his own original hard work from getting ripped off and used without his permission. Basketcase, you are not using that webcomic in any way, shape, or form without permission, are you? The title is pretty much irrelevant. Don't worry about it.
And for chrissakes, man, don't even THINK about using it as an excuse to cut corners on the quality of your work or to delay posts any longer than they already are!
Post on, Basketcase!
