I don't think it's random with the trigger icon, but planned. DocJohn really doesn't want anyone triggered I guess

The outside column where the second one shows up is the admin/mod column (my words, I have no idea what they call it ) That's where they put the stick pin or lock or whatever it is they do with a particular thread. I think DocJohn made the trigger icon a default icon in that column whenever someone puts a trigger (trig) icon on their originating post.
