OK, that thread has been restored.
I definitely want the forum to be as open as possible, as free as possible. Since the very beginning - over three years so far, I have only deleted one thread except for spams. I exchanged maybe about 20 PMs with other members before the deletion, the deletion kept one helpful member stay.
I have never banned any members expept for spammers. On this forum, spammers refer to those members who come here only for promoting their products or websites, they don't make a single post with their own words.
I'm very strict on spammers, I believe no one like them.
