Mike, I just commented on your shout box post, but here are my thoughts in post form.
EcoPowerPerformance.com has a great ring to it. Would it be possible for you to secure both EcoPowerPerformance and EcoPowerPerformanceForum? In doing so, you could have the first dedicated to your business and the other reserved for the forum. If that is the case, I would suggest using
EPP.com and
EPPF.com as opposed to EB-PP as you had previously stated. My suggestions are not intended to offend. It's your money and your baby and I'm willing to support whichever name you ultimately choose, but my marketing background tells me that the consistency is great for name recognition.
