Marking Threads As Read
 

So I can't stand seeing the green unread thread symbol. It's not bad, actually it's kinda pretty. I just can't stand it being different and there. So what I used to do with threads I didn't follow was click on the last page and a soon as it loaded going back to the thread selection page. However, I'm trying to avoid the spoiler page so much, and very occasionally I glance at something I wish I hadn't. So what I want to know, is if there is a way to mark a thread as read, without actually going into it.

You can mark an entire forum as read by double clicking on the green icon.

Read all of the threads you want to in a subforum first, then do that and you're all golden.

Whoaaaw, I did not know that. Nice :D
