Ah here we go, this gear is super helpful. I wasn't really looking to block specific tribes (I wouldn't have joined them if I didn't want to see them), I was just bothered by the flood of comments that hid the actual threads. Now I can turn off third-tier comments, at least. Is there any way to quickly see what tribe each comment is posting on? I see each comment has a "Posted in:" but it doesn't say the actual tribe.
