To the best of my knowledge, the site's data base and other components were put together with Joomla. The forum is Kunena, and yes, all of it was open-source.
If one reads the news reports concerning the "Heartbleed" problem, one notices that the security problem deals specifically with Secure Socket Layer issues. We do not, and have never, used SSL for this site (again, to the best of my knowledge and recollection).
We have no need of this, as
we do not collect, nor do we store, any sensitive financial information about our members. Our donations are handled through my PayPal account, which has long since fixed it's vulnerability issues.
If it makes you feel safer to change your password for this site, by all means, do. After all, many internet security experts caution that you should do this regularly anyway. Rest assured, however, that we will continue to monitor the situation. If we feel that our members might be compromised, we will alert you all as soon as humanly possible.
