If the above request is is too large for a simple implementation, then please consider adding some tokens to the email templates.
This token is available for Event List templates but not Email. How about just making all of the Event List tokens available to email templates?
[URL] - A link to view the event page makes good sense.
For these two I am seeing links for these functions on the Receipt Page (http://domain.com/Events/ctl/Receip...ItemId/###
[URL:Checkout] - If someone wants to pay online after choosing Offline, it'd be convenient to have the link in their email. The link I see for this is: http://domain.com/Events/ctl/Checko...hod/Paypal
[URL:Modify] - This would allow someone to modify their booking after they leave the Receipt page. The link I see for this is: http://domain.com/Events/ctl/BookEv...kingId/###
Thank you for your consideration.
