After a guest posts a new topic in the forums he will see an error page, that he is not allowed to view the topic.

I suggest that the poster should see a page, that his content will be reviewed.

He's talking about moderated content.

It doesn't matter if it is a guest or a member, once you post something what needs to approved, you'll see the "no perm to view this" errormessage, which can be quite confusing.

I agree, that itwould be user friendlier if the content creator would get a more informative message.

We've changed it so they go back to the forum index with a popup message  

Great, thank you.

At which release can we expect the change?

I would like to know too when we can expect the change?
