I wanted the chat feature, but those other features came along in the package, so I figured, why not? But since Invision is hosting it, it is a monthly fee. If the forum blows up and becomes wildly popular, then I might have to consider other pricing options, but as of now everything is running smoothly and within my pricing plan.
The mods will update it. I only did this because if too many people start messing with it, it will get extremely messy.
