You mean that thread owner like president has the indemnity that no body should and could say anything about him, even if he is wrong.
I like this rule. The thread owner can criticize, ridicule any fellow member on his and in any other thread any way he likes, but he has got indemnity as he is owner of the thread. Nice thought.
Ok. I will not post here but ask your friend to:
1) take his daily dose of Nido so that he could grow up and could think like a mature person and stop lying, insulting and ridiculing other fellow members. The other people also like to be treated like, you want to be treated by them.
