Member support on labITpro goes straight to the person who built the labs. Whether a step didn't make sense, a lab won't launch, or you're deciding what to study next, ask here and you'll get an answer from him, not a ticket queue.
Senior infrastructure engineer turned trainer. Tom designs, records, and narrates every labITpro lab, and has taught Azure, Active Directory, and Windows infrastructure to hundreds of thousands of IT professionals.
This is member support. Content questions and account questions both come to the same inbox and get a personal reply.
Direct access to Tom for lab, exam, and account questions comes with the All-Access Pass and the Team Access Pass. Pick one and this form unlocks as soon as you're signed in.

Tom does. There's no support team in between — the person who wrote the lab reads your question and writes the reply.
Usually within a couple business days. Anything that's stopping you from getting into a lab is answered first.
No. Replies go to your email only. If a question comes up often, a general version may be added to this page, without your name.
Yes. Study plans, exam strategy, and real-world Azure or Active Directory questions are all welcome — those are often the best ones.
Either works. Course-specific questions are best in the Udemy Q&A so other students see the answer; lab questions and anything broader belong here.
Please do. Requests from learners decide a lot of what gets recorded next.
