The way Steinbergs forum works is you do have to have a registered version to post in that products forum. Example, I can only post to the LE forum as that's the version I own. I cannot post to the full version forum. Until I upgraded Wave lab I couldn't post there either, I had to post in the legacy forum. So what would happen is I couldn't post here as I am only a legacy product owner.
You can post in other parts of their forum. So here it would be unregistered people would post in the Hardware or Coffee house.
