Is it possible to include a setting for Ticket Types were there is no Limit of the capacity of each ticket? I know a lot of times in components they have you put a "0" in the field and this means unlimited.
Leaving it blank seems to be the right way to achieve it.
On another note when testing I chose the option to collect member information for ticket types and when I choose multiple quantities of tickets it didn't present the member information like it should. Could be a setting I missed.
