Oh yes, a very good point there Gothi[c]!
If possible, users should try to access websites via https, especially when they are transmitting sensitive data. This includes passwords, credit card numbers, your SSN; basically anything that a website asks for to identify you.
There are numerous websites I haven't signed up with because they don't let me use https; gulli.com for example reserves use of https for admins and moderators.
And if you don't have a choice, like on my website, make sure you use a unique password, so I can't break into you other sites and services.
