Likely the reason that replies werent allowed is to avoid any flames, and thats understandable... especially considering these are the official AMD boards. However, i think with careful moderation (both by moderators and users using the 'report post' function) replies can be supported successfully.
That forum has great potential, but its stunted by not allowing replies. What makes posting your system specs fun is getting feedback from other users. It's not fun to watch your post get buried on page 214 after a week and never return. :/
