How do you make your account more secure? Should I abandon Crypto2Alt and use this new AsicDeals account instead?

I have NEVER accessed Bitcointalk from any public computer, always accessed from one personal/private desktop over Ethernet. So, wondering how my Crypto2Alt account got compromised?

Granted, I had not set the Secret Question/Answer in my Profile. But how someone managed to change my Bitcointalk Crypto2Alt account password without it getting confirmed from my email account?
