G'day, David, I think you're in plenty good time, as it's only just past 7:30 am US Eastern - and registrations close midnight tonight (US Eastern time).
Kathleen will be along at some time to officially welcome you to the Wizards of Aus, meanwhile, I don't see you on my list of those who have hats (seems you were a tad Twisted the last couple of 'Thons), so here's your Wizard Hat.

They don't do anything, as they're just a fun thing I give to Team Aus members. (Some folk ignore them, others add them to their biography, others may choose to display them as profile images, or use them in email. Choice is yours. )
If you choose to add it to your profile's biography in any way, you don't need to upload it to Wikitree, as it's already here, just use the image code (either the {{code}} or the [[code]] will work) and the image's ID# which is WizardsOfAus-80.png (If you would like to use it as your primary image (can't think why, when you have a photo of you there!), just send me a private message and I'll send a copy to you via email.)
