We have a section of our forum that has been set with "Users can see topics posted by other users". Is there a way to create a sticky post that is visible and readable to all while keeping all other posts under the above topic post restriction? Intent: we would like to be able to put readable sticky post with guidance in it regarding how to use the area of the portal. I know its a long shot but had to ask.

You can use the forum rules option to show forum-specific instructions in the forum listing view. 

Or you could use an announcement targeted to that section only.

Thanks. Both of these were great suggestions. We ended up going with the rules option. Thank you for the feedback.
