Can happen on any website. As long as the password has a salted hash then that's not a major problem.
Sites where you key in lots of personal details may be more of an issue - unlikely to have an kind of encryption and certainly not one way hashed, otherwise the owners of the website wouldn't be able to use the info.
UKC?
Who would bother? * Not 1.8 million names & email addresses to harvest on UKC.
Though you should still have a different password in here to every other site you use, especially if logging in with the same email address.
* someone that could hack UKC get your login details and guess that you use the same details for facebook etc - they then have an entry point for a crack on another website.
