1. Show who viewed the thread.
I am curious sometimes to see who has viewed my thread or who has viewed a thread I'm viewing. I don't see how it would harm anyone if this could be shown, and if people want to remain anonymous, they can always set their online status as invisible.
2. Show who has repped you.
I like to individually thank everyone that reps me, and I'm sure other people are curious to see who has repped them as well. This would be a great addition.
3. Be more firm about spamming in the intro threads.
It's alright for people to post when someone makes the intro thread, but bringing a bunch of threads back from weeks before in an obvious attempt to gain post count just doesn't look good. Some people actually try to post legit posts for +1 to their post count.
That's pretty much it. I love clraik the way it is, these are just ways that I think it can be better
