Guest vs Logged In Content

[mosaicpro]

Hi Mozzers

I have a client that recently launched a q&a and he has the answers hidden by registering  for free you can see the answers. It's a free community.

Now the question comes:

Google will not get the entire page only the question content which I think is bad. What option would solve the issue.

Have thought about making the answers hidden through css... so if you're a guest the answers are display:none .

But it has to be a better option than dirty things like this

I would have the answers on a page that you go to when you press complete, and have that page in my sitemap.xml, or like you said have it display none, but apears when you click complete, haveing text hidden is not a problem as long as it is displayable to  the user somehow, like clicking a button
