Hi @Piscaro! Welcome to FUD!
Yes, @TiaG is still around. She will be here at some point.
Just to let you know a few things. If you put an @ in front of a user’s name, it tags them so they will be more likely to see your post.
Also, if you have not done so yet, I hope you will post on our “Welcome, introduce yourself here” thread:
https://forum.fudiabetes.org/t/welcome-introduce-yourself-here
It’s a long thread, over a thousand posts on it. So you can either read them all or just scroll to the bottom and introduce yourself. 
Anyway, welcome to FUD!
And BTW, I have used insulin that was frozen. It still works.
