3DMentia does it, and no one seems to care. Not sure why it matters in this situation.
He proudly informed the forum that I am on his ignore and so is urbandreamer.
As for how to do it, just go to their profile, and click on the User Lists drop down, and then choose ignore list.
It is important because if he is not going to get be told to stop thinking for others and taking everything opponents say out of context, then the only option is to ignore him.
Either that or do what others recommended doing, don't join in any threads he is on. I think ignore is better.
It is consistent that a new member magically pops up to chastize older members.
