Featured content, Text widget, Promoheadline, Languages

Hi there, Thanks for the great Adventurous Theme! It looks good and customization seems easy (even for IT illiterate like me..;). Well, easy with a couple of questions, please. 1. How to link individual post Categories with individual Featured Content images? I understand how to add link to the Featured Content but haven't been able to figure out proper link syntax to Categories. 2. How to include internal link to the image inserted into a sidebar text widget? 3. Promoheadline: how to change action button into contact form (name & email)? 4. How do you recommend to best handle email automation? I so far installed Contact form 7 plug-in but haven't played with it enough yet. What about integrating a software like MailChimp? 5. How to translate e.g. "Posted on February 12, 2016 under in XXXX | By XXXX. | Leave a reply | Edit" and similar default texts into another language? 6. How to run a web/blog in two different languages? End-game: structure similar for both, content may vary. Enough (for now ;) Thanks a lot, Dan
