My idea is to go back to showing how many members are in a sub and show if they are active.
Seeing how many members are in a sub can affect if I join, post and/or comment. I think I'm not the only one.
It can go either way whether there's too many or too little members in the sub. It's nice to see the amount of traffic but I also want to see the number of members in the sub and it would be nice if it showed how many members were active.
