One thing that helps me is like today when I came on line there was an avitar that triggered me so I wrote the persons name down then when I clik on the message board name I read down the list of topics in that board. The next collumn is who the original poster who started the thread. Before I opened a thread I made sure the poster was not that person with the avitar I was sensitive to today. then only after I knew that poster wasn't that person did I open the thread. I know that does not prevent my seeing it as a part of the threads the person didn't start but was replying to but it was a start and a way to take care of myself.
