Robots are the bane of the internet for posting unwanted content onto innocent websites. Linear employs many techniques for ferreting out robot content from the valuable visitor contributions, but ultimately, clients may wish to initialize a "captcha" element. Once successfully completed, a web visitor will not need to complete the Captcha - or if a member has logged-in they will bypass the Captcha.

We've tried to make it as friendly as possible, but there will always be detractors. Once engaged, the Captcha feature will apply itself to Forms, Calendar entries, Guest Book entries, Letters to the Editor and more.
