It's good to get new threads going that are fully new content, but even at times having threads and no replies is just as bad. I like to see threads with many repliesI used to think it was part of my member's responsibility to help build up the forum by creating threads. The problem is that Christianity Haven is almost 6 years and some members who are very active are reluctant to create new threads. I'm the number one thread maker!
One thing when I do hiring of mods is to let them know it's better for us if they help create threads. That of course isn't always followed by them but at least they know my desires.
