I want guests to see topic titles but not their content

Hello!
I have a question about a problem which I am not sure if it can be solved.

It's about how the forum is viewed by guests.

I want the guests to see the forum in this way: Viewable categories, viewable topics but just the topic titles and not the answers the members have written in each topic. I hope I am understandable.

So far, the guests can see the categories and subcategories but they can't see the topic titles in each category and I don't know if I have the option to make that viewable.

Thanks a lot, in advance.

Hmmm, I meant that I want guests to see the forums and all topic titles in the forums but not the answers.
Thank you!

Thank you a lot, but where I have to put those tags?

I put them In the first message of a topic, but then the following replies are viewable to everyone.
Only the topic first message is hidden.

You mean only the first post should be visible? Rest should be hidden?

No, (s)he means, that guest can only see topics titles in categories. They can't look inside the topics.

(that would be visible)

I think, this isn't possible right now.

Ok, guys, thank you very much.
I mean what Tonight says.

Sorry, but that is not possible.

Thank you for declaring!
Problem solved
