Forum Blocks (Sidebar) question
 

I have the Forum Blocks (Sidebar) active on my forum, my users can collapse/expand it using the little side arrow buttons. Is there a way to force the Sidebar open at periodic intervals (i.e. every 15 days, or even manually) for all users where they would need to recollapse it (if they want it collapsed).

I feel that a lot of my users may have collapsed the sidebar initially and more or less forgot about it, now when new content is added to the sidebar they are missing out on it.

Any help would be greatly appreciated.
