Welcome Helen! I do remember our chat (although I didn't make the connection when I first saw you join up).
You sound like you're in a fortunate position in that your UX role has come along before getting a heap of experience under your belt. It's certainly the other way round for a number of folks, but it's inspiring to hear that you've successfully moved sideways in your career and bring a heap of experience in marketing and other areas to the role, and now want to solidify your understanding of UX stuff. I met a lot of people at the book launch in Sydney last week who have moved from visual design to a role that has "UX" in the title, but in reality they are beginners and eager to get back to basics in many ways.
Anyway, welcome aboard. Glad to have you. Sarah has mentioned the online courses we've pulled together, but I hope we can help you in your journey in other ways too.
