This is a response to the question about including HTML in Event descriptions here: http://www.imiscommunity.com/complete_newbie_need_help I'm posting it here so I can attach a screenshot.
Something else that might help...
The Event Directions field, from Define an Event in Desktop, is rendered as an asp:Label in public view and template sites, so it can include HTML formatting for bold and hyperlinks. The attached screenshot shows the desktop setup, with html in the Directions field, and its effect in public view. I didn't check to see how confirmation notices would handle HTML, so you'd probably want to check "Suppress printing of directions on Confirmation Letters".
