Active users as a % of registered users.
I know of a forum where about 5% of their registered users are active.
That seems low to me, especially for a site that has been online for many years, but I don't run a forum, so my knowledge about these things is limited at best.
So, is there any kind of percentage that shows up as more or less a norm?
