I don't know what the previous thread said. Perhaps the topic became too hostile or abusive - probably. As a Moderator, I peeked to see if it was "trashed"...I won't do that again. "Dumpster Diving" on GBO is not for me.
Keep it clean, above board, and above all friendly.
As a General Rule, if the discussion is not something that you would hold with your Grandmother, Mother, or Sister then it probably won't make the censor's cut here either.
