Thanks for the help, Nik!
Sorry, Nik, I shouldn't have muddied the waters with my comment about the MailChimp integration...let's please step back from that factor, since i don't want immediate notifications and have disabled the MailChimp integration for now.
The real issue is still the fact that my RSS setting is set to "introtext", but the feed displays the entire text.
I am using MailChimp, but simply using an RSS-to-Email campaign and the RSS feed generated by EasyBlog, blog?view=latest&format=feed&type=rss.
If you view the RSS URL posted, the "read more" link is generated, but it is at the end of the a very lengthy post, not the intro text. Even the default "Subscribe via RSS" feed, /blog?format=feed&type=rss, displays the entire post, rather than the intro text.
Before I replace any core files, I want to make sure that is the resolution in the blog.php you sent, and it is not specific to the MC integration!
Appreciate your assistance!
