Firstly let me say I've had no problems using this plugin. Thanks to the author for his efforts.
Secondly, any chnace in being able to manually change the upper value the two number we add together to verify our advert? Some users may find it hard to add 47 + 88 (believe it or not). I've changed the plugin core to read 10 instead of 100 but i don't want to do this on each update... thanks.
