Am I able to tailor Email digest content differently for various groups that I have set up? ie. enable Forum content for all, but select what groups are able to see Blog content updates ?
There's not a clean way to do this as the email digest is universal for the whole site, but you could add a condition to the email digest template that checks group id and does not render the section (ie render nothing) for certain group ids. Again, this might be kind of messy as it's a workaround.
