No worries!
1). The contact info is nothing SmarterTrack provides. In fact, the only thing that we utilize that is SmarterTrack based is the FAQ frame, articles, and ticket submission page. Everything else is customly done by our companies programming and design teams. So for all brands that have different contact info, that's all wired in via Javascript I believe.
2). If you have multiple brands set up, you can distinguish which parent/article is for which portal. You can have any combination (assuming your article applies) which portals have which articles, or if they apply to all your brands, simply select "all", which allows that article to be viewable on each brand's portal.
