In the early hours of Tuesday morning, the server that this site is hosted on was the subject of an attack through another site on the server. As a precaution, we are taking the view that all user's credentials are compromised.
There are no security issues with regard to this site and your login details as no sensitive information is stored on the server and registration to this site is open to all, so a compromised login is effectively useless to an attacker.
However, if you use the same login credentials on other systems such as email, facebook etc. it is strongly advised that you change your password on those systems. The risk of such an exploit is considered very low risk, but we still would strongly advise that you change your password on those systems where your name or email address are searchable.
This is only necessary if you use the same login/password combination on other more sensitive sites. It is always advisable to use different levels of credentials on different websites depending on the possible consequences of a security breach.
We appologise for the inconvenience.
