Is there a way to force users to accept changed terms of use? For example, when a user logs in, it gets a message that he has to accept a new terms of use, together with a link to the document and a checkbox.

This feature could be related either to a registration disclaimer, or to a separate document like the one at XOOPS site - a wf-channel page.

BTW. Is it possible for a user to see the disclaimer he had confirmed during registration?

I did this hack several years ago for an older version of Xoops.

It may still work, but I have no time to check at the moment.

If you update it, please post the code here on XO as I am sure others may find it useful, especially with the new cookie regulations in place.

At a glance - this hack makes the checkbox appear always. Maybe it is a good starting point, however I need it to appear only when I want (i.e. when TOU is changed) and appear not for everyone - those who accept it, will not have it displayed any more. That means that accepting TOU should be recorded in database and checked on every login.
