I wanted to change a bit the lloks of smartor's Anti Robotic Register Flood. Some of my users didn't manage to spell right the text (don't know why).
The changes made to the original mode where:
1) The image is created from within php, not loaded from files. With a look seen on some comercial websites.
2) Part of the Database management is done inside the picture file, therefore it seems easier to install.
3) Made changes to the randomizing function to obtain more randomness.
And I think thats about it.
You can download the file from: http://www.terra.es/personal/antispam/yaarrf.zip
Hope you like the modification of the mod.
Sorry for my poor english.
