I have to disagree. I prefer the forums seperate.
I could care less what the people in Europe are doing with their Desire HDs. The Inspire is a US phone on AT&T. It has a seperate identity.
Keep in mind even though they are pretty much the same phone, they run on different networks, have different radio software, and are supported by different cell providers. People's experiences will be different than their European counterparts.
Please keep them seperate.
