just because it is not an important section of the forum doesn't really mean it should be removed, the section exists so people can talk about things they are interested in but aren't related to any boards available in the forum.
why not remove it totally from the board so that whenever we don't see our post we know it has been deleted completely from the forum.
I am confused about this part, not sure why anyone would think that their post will be on the off-topic board if they can't see or find their post anymore.
