Thanks - I did it a little differently - I placed the "I accept" and link to my TOU in a little convenient option that adds html to the top of a user post.
However, this is not an acceptable solution. Terms of use MUST be accepted actively, e.g. user must physically check a box or make a selection to agree to the terms of use. If this does not exist, there will be a debate about whether the user has actually agreed to all the TOU on your site.
I think that "integration" means that users can be registered in a wordpress database and are synced to q2a? If so, at least for my sites, I can send them to WP to register and accept the TOU and then the user can navigate back to Q2A. Certainly not ideal but it works.
