I have made this silly mistake in couple of weeks ago, I mistaking posted a topic in off topic board meanwhile was meant to sit in beginners and help section. Thanks a lot for this guild, and it's a good one OP, I'm keen to learning new thing onboard or outboard of forum.
When people create a new topic, there is an important hidden option: Self-moderated. They have to choose the option at beginnings because creators can not choose this option later (if not choose at beginning). In the other words, it is a sort of
one-way process.
There are board like Metan where the option is not allowed so that if you have a self-moderated thread in Beginners & Help at beginnings and move it later to Meta board, the self-moderation rights will be disable automatically.
Moreover, you can not choose this option later even if you move the thread back to Beginners & Help.
Also please see:
In most sections, you now have the option of marking topics self-moderated when creating them. In self-moderated topics, the OP can delete replies. The option for enabling this is under "additional options". Topics cannot be converted to self-moderated topics after creation.
In addition, thanks for this great teachings. I think I'm gearing up on a greater wheel.
