Thanks Alex.
It seems to me (from looking through the available anti-spam mods) that the use of image verification is 'the' way to head off these spam-bots? Just out of interest, would you, or anyone, know if there are other mods that prevent this misuse that is different to image verification? If there are any other methods, has anyone used one alongside Alex's mod.
I intend to go ahead with this mod (thx BTW :)) but am just interested in other methods to control these ^&*(^*&^%*((*%(*^%&())(*& ARRRFGGHH!!!!!! Man, they make me madder than BANKS!!!
