Recent Discussion Forum block expanded.

I have expanded the recent discussion forum block that shows up on the front page of SermonIndex from 12 forum threads to 15 so more of the recent discussed topics will show up longer on the front page of the site.Also above the recent discussions block there are 3 featured threads that will change, that space will feature events, announcements and other threads that are notable and should be paid attention to.feel free to share any comments or suggestions.
