If there is an overall limit on registration, the available count appears on the event listing page.

But if registration is limited in each registration type, that is mostly invisible to registrants and the process becomes confusing.

o The number of open spaces in each registration type is not shown on the event page. It's only seen after the person starts to register.
o The event page doesn't show that a type is sold out.
o Sold out types don't show during registration, unless the person notices that it's not in the list.
o If only one type is still open, the person is automatically registered in that type. But that's not flagged except quietly at the top of the page. They may continue registration expecting to be given a choice later on.

All these problems need to be fixed.
