eladmarmor But i was told that JA content is designed to work only on some custom templates that you created
You can use Ja Content type on any T3-Framework based template, so you can use it also on T3-Blank since it is T3 based , the documentation guide i linked above is based on JA_Teline_V Template and JA acm Module but only as example , If you know how to create new content type following that guide then go for it , otherwise you can hire a developer doing it for you.
