Hi,
As far as I can see there is not way to, for example, show the last 1000 lines of history. The best I can see is 'last --nolimit'.
It may also be useful to provide a way by which to show all messages since a given time. In our IRC channel, people connect and disconnect as they come in and out of network connectivity and often a summary of what has happened since they were last logged in is needed.
Cheers
