Integrating Vanilla with CMS
Is it possible to make close integration as with Addons application on this site?
I want to see all related discussions below article and see "Related to ... " message on top of the first post in each discussion.
Any ideas? I know that AddOn app uses simple AddonID parameter in URL.
I am not using WordPress, it is rare CMS.
