This morning I posted beta-2 of Email Users 4.6.11.  This build addresses a bug with the Post Excerpt recently reported in the WordPress Support Forum.  I suspect this bug has been around for a long time.  Email Users was making a call to get_the_excerpt() which it turns out, should only be called within The Loop.  I have fixed this bug and and the plugin is now looking for the excerpt properly and more importantly, my test posts are behaving properly.

Please report any other issues and I will do my best to address this ASAP.  Since this is a pretty serious bug, I will likely release an update within a day or two if I don’t have any further bug reports.
