I need a disclaimer, so I'm using your plugin.
I have a problem though: the disclaimer set in the admin is being saved (checked this), but it's not showing up anywhere.
Opened your plugin file and I think there is a bug in the get_disclaimer function.
This function has the attribute "$nl2br", but inside a test is done on "$mode" (only when $mode is true, the plugin requests the disclaimer text?!?).
For now, I've just disabled the test ;-)
