User need to click agreement before posting a Thread

[osix]

I know there is VSA advance forum rules .

is the something like User need to Click on a Box

And maybe Answer a Question before being allow to make a post .

i try the Captcha but is too complex and is not good for new forum as it do not improve posting rate form new user .

so i am looking for a much simple process

making user Click on a Box just like DP new thread .

and maybe adding a Human verification in a form of answering a Random question
