Related to Is there an easy way to discard all messages waiting to be reviewed?, one might also want to accept all messages (if, for example, there was a mistake in the list config). There is no convenient checkbox for this in the interface (since discarding is a much more common task), but you can use a bookmarklet to change all the messages from "Defer" to "Accept"

javascript:function%20approveAll(){var%20inputs=document.getElementsByTagName("input");for(var%20i=0;i<inputs.length;i++){if(inputs[i].type=='radio'&&inputs[i].name.indexOf("senderaction-")==0&&inputs[i].value==1){inputs[i].checked=true;}}};approveAll()

Be careful with this! You might want to review the messages before hitting submit to avoid accidentally spamming your users.
