funCap is a very basic tool for form protection, it's main use is for fun.For example, if you haven't got a server with the GD library extension / support then this is a perfect temporary solution.
I strongly suggest you use a capcha image verification tool if you do have the GD library feature as this will be much safer and protect your forms better.
It's quite customizable, uses a little bit of a template naming schema, you can change add your selected words and add sentences that replace the word in the particular sentence.
Suggestions welcome.
Interesante.
