There is now daykill functionality for FM.

The host/OP of the thread must first enter [ enabledaykills][/enabledaykills]

Then anybody in the thread can do [ daykill]username[/daykill]

It will immediately close the thread so nobody will post after the kill.
It also @ mentions the username you entered so they get a notification and hopefully realize not to post anymore in future days

The enable day kills bbcode must be done anytime votes are reset (e.g. whenever day ends)
