Tips to give to end users to avoid having their online email (Gmail, Hotmail, etc) being hacked? [closed]

I'm seeing a lot of online email accounts being hacked lately. I'm guessing someone hacks into the account and then accesses to send the spam I'm getting. (It's happened to 2 friends and one customer in the last month).

I'd like to post some suggestions but thought I'd see if there was something good out there (I looked and didn't find a good simple but comprehensive one).

Solution 1:

The US Government, through the FTC, has released a very large volume of end-user information about how to protect themselves on line called OnGuard Online.

From the main page, if you click on 'Topics' and start browsing through the list you will see several that relate specifically to email and/or phishing. I feel like they've done a great job of compiling the information and making it easy to understand.
