It's from Recruiting~ thread.
It seems that the users of the newsplus board want to change their Samba24 from 120 to 20.

Currently in newsplus, the interval between one's posts is 120 seconds.
Regular users there discussed the interval and now they've came to the conclusion that
it should be 20 seconds. So I'd like you to change the current interval to 20 seconds. Thank you very much.
