Tikki: In the forum list there is the topic of GENERAL & then under that is Community Guidelines. It says the trigger icon should be used with "triggering" posts (or something like that). Icons located at the left of the box you type in; it says "post icon" & then you can use the arrow below to open the box to see the options that are available & there is one that says "trig."

I'm not sure if "triggering" is defined adequately anywhere, but as far as I understand it, it would be anything that you think might be sensitive & could upset someone such as child abuse, suicide, death of family member or friend, drug abuse, etc. That kind of thing.

Probably any kind of destructive or dysfunctional behavior would qualify. I think it is a judgment call, but I missed the boat as I wrote about OD.--Suzy
