Thanks for taking the time, Stephen.
Now that I have the thumbnails working using the [eo_events][/eo_events] tags (or if I prefer the entire event description in the event listing with its images), I am happy camper.
I will look forward to 1.7, but I love shortcodes as well. What took me a second was realizing that you were talking about a shortcode with parameters, as it were, in the discussion on event_list_shortcode in the link above. I thought you were talking about something added to the PHP; my ignorance.
I would put a word on the page with the shortcodes, showing the useage; I looked at those shortcodes and I assumed that was it, the rest was code.
Keep up the great work, I do thank you and if I get more folks looking to put together websites using your plugin, I will make you a contribution. So far I have one client, but I'm hoping!
