Direct URL to Event Registration Form?

Hi, when building events in the past, I've noticed that the "event page" generated by Luminate Online, along with the basic event info, contained an RSVP button AND an envelope icon off to the right side of the page.  Both button and envelope icon ostensibly took the user to the same place, the event registration form.

The thing is, the RSVP button took the user to the event registration form via a URL (such as, for example, http://support.uwkc.org/site/Calendar/1261379623) that when entered into another browser manually, confusingly took the user to our event calendar (even though the event was kept private).

Conversely, when the envelope icon was clicked, the user would arrive at the registration form as well, but, with a URL that could be used to get to the registration form directly, bypassing the automatically generated event page.

Perplexing UI design aside (why two icons going to the same place on the event page?), I'm no longer seeing that envelope icon on an event I just built, and can't seem to arrive at a URL I can use on my (CMS) landing page that will take the user directly to the event registration form (I very much prefer to bypass the event page, as it seems bad UX to have the user indicate they want to register for an event, then be presented with the event page requiring them to click an icon again to actually register). 

I don't want my users to land on our calendar (confusing), and I don't want my users to have to click through another automatically generated event page to get to the registration form. How can I get the direct URL to my donation registration form?

Thanks.
