I hope this is the right forum to raise this issue?
It is possible to create this product?
That allows to establish a topic as "required reading" for newly registered By default, if you start an important topic (for example, the forum rules topic page) and you want all your members to read it. When this is in effect, the user who has not read the topic yet will be automatically redirected to the interstitial page and will be asked to read the designated topic first, and create an interstitial page in Sitebuilder so that they can customize it.
Once a user reads a topic, they will not be bothered to read it again.

And to be able to configure all or some groups of users that must read a topic.

Thank you and excuse my English for I use google translator
