As of today, whenever someone registers for an event created by Slick.events they will automatically get an invoice! This is sort of exciting and something that really helps the attendees with their accounting for the expense.
I hoped to be able to sort this development out in one evening but it turned out it required a bit more effort than that, then I realised, what good is it do launch a new feature without documentation. So I had to spend some time on that as well :)
