Would you include a link on the rules so they can continue with posting?

Yes, i've forget this,but the link must appear only when they post for the first time.

Yes they have to do that but it's general rules , i have specifics rules for every forums i have and they didn't read them before posting.Some people register and send their first post one month after,of course they forget what was written in the rules.

(Also, don't they have to read them before they sign up?)

First, thanks for all the answers in this forum,i've found a lot of solutions to my problems here.
I would like to force the registered users to read the rules of each forums i've made before posting their first post (and of course only once).
Just to be sure they have read the rules before posting for the first time.

Any idea ?

I think the modifications have to be done in post.php.

1) Check if he is a registered user
2) Check if it's his first post
3) Yes -> Read the rules
4) No -> Post

Thank you.
