Hey there folks. Thanks for the notes here.
Shannon: if I understand what you’re trying to do here, couldn’t you add the blurb you want in the loop into the “Excerpt” field and leave the regular description as-is? Or, create the blurb in your description field; add the “Read More” link; and have the rest of the blurb below, thus hidden behind a “Continue reading” link for users on the frontend? Let me know if one of those will do the trick or if I’ve misunderstood the issue here.
John: for the widget, you should be able to turn on the Events List Advanced widget under Appearance –> Widgets to display the list in that simple format. Have you given it a go?
Let me know if either of you still have questions/concerns here and I’ll adjust my response accordingly.
