UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Photo Gallery Reply - Display in Recent Posts?

I noticed that when someone replies to a posting in a photo gallery I've setup, there is no indication in the "Recent Posts" island. All the other forums show when someone has posted a reply. How do I get the replies in a photo gallery to also show up on the "Recent Posts" island?
