Hi,
I've just received my Yubikey today and am using it with LastPass
I tried to join the forums before and was not able to as I needed a yubikey. I though this was a bit odd as it restricts potential customers from communicating with people who already have a yubikey. Personally, I usually converse with users using a product to get a true idea of its effectiveness etc.
I would suggest that the forum have a 'public' section for anyone to access and a restricted section where only yubikey owners can make posts.
What do you think?
