Being using Ninjaboard for 6 months or more now and it's been great for us.
One small problems: if someone hasn't uploaded an avatar there doesn't seem to be a default to fill the space. I've noticed the same on this site.
That doesn't look strange here on the forum, but it does when shown in the Ninjaboard module. Instead of an avatar, you just see a blank space.
Any way to have a default avatar?
