| - | * Registration | + | |
| - | * If user has **passed** the CAPTCHA, but mistaken in some other field of the form (the form is displayed again for user to correct the data), **do not** show the CAPTCHA again. I.e. user must pass the CAPTCHA only once to register. | + | |
| - | * Here may be used the simple CAPTCHA kind of "Are you robot? Yes/No" Just use the random ''name'' for ''<input>'' or even ''name="agree"'' for "Yes". This will protect from common robots, but not from targeted attack, so this may be an option. Delay this for (pun_antispam 2.0) | + | |
| - | * Guest post | + | |
