I hope to have both a html table and a GD bar graph. Im also going to add support for GeoIP to report by country and much better sorting in the logs system. Ill certainly add a date search timeframe to the logs as well.
Ill sneak in an option to PM users each day with a breakdown on the blocked/logs registrations as well.
