Nope, for some people there's simply no ability to reply. The majority of keys given out are "server cattle" keys. I've only heard of a few rare people who got their keys for Phase 3 and can post.
An old alpha member told me only they can post in the true feedback section forums and most people have to settle for posting in the discussion forums.
That's the most insane way to run a beta I've ever heard of.
The entire point of having ordinary players test your stuff is because they'll think of things you didn't. You want feedback from all these people (btw reading forums is what community reps are for) because they have an additional pair of eyes and hands (usually) and the can do things that someone else may just have never considered doing.. like let's see: What if in the middle of a guildleve, I stab this thing, and then run down this hillside where he can't get to me, the hillside is a zillion yards away, but I can make it.... How many people with feedback access are going to necessarily think to do that, ok, now how many of those represent every class possible, or disciples of the hand/land?
More people = more people breaking things = fewer bugs in your game
