Before you get cracking on the live version of your EventHQ you may wish to do a little fiddling first. You can enter an event into test mode when setting it up and then any associated orders will be classed as test orders. You can then create as many (free) test orders as you like.
If you do decide to do this then you can always purge your test orders afterwards. We would highly recommend doing so as it will keep your database clean and tidy.
