OK...I've gotten past the "where do i put my K2 sub-templates" stage, and am ready to get into the customization of of the files provided:category_item_links.php  category_item.php  category.php  item_comments_form.php  item.php  latest_item.php  latest.phpI am beginning to see the logic behind the process; but I also have questions:(1) fonts/spacing is probably managed through CSS...how do I add my own custom fonts?(2) My first customized template will deal with my front page ('default' folder copied to 'fpage' folder for customization); what is the relationship (if any) between my customized fpage and extensions like RokTabs, RokStories or RokNewsPager?
