[Enigmail] New to Enigmail and having a question about the validity of signatures

[Luke Chen]

Hi guys,

How are you? This is my first day using Enigmail. I have been using 
Ciphire for a while but unfortunately it was terminated a month ago. 
Then I discovered that using Enigmail isn't as hard as I thought! 
Anyway, I am just wondering if someone can help me answer this question: 
There doesn't seem to be a central Certificate Authority for validating 
the public keys. How do I know if I can trust the signature from a 
particular address? Thank you!

Sincerely,
