Going back after 4 months at home

I am nervous about technology changes while I was away. I have read a lot of threads here and could not find my exact situation. I have been taking an online course. How did you get back in?

Refresh the main tools of your field with a few tutorials. It builds confidence.

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
