I've added (X viewing) to each forum listed on the main index, which indicates how many members are viewing that forum at that time.
Unfortunately at the moment it doesn't include guests, maybe that's something i'll work out in the future.
If there's noone viewing a particular forum, it will be blank.
It's just a little feature I liked, seen at the CN forums. Apologies to anyone I disrupted while coding it and causing database errors
