It has come to my attention that Firefox is giving people a security warning when visiting DSA. This has to do with our security certificate and is an extra layer of protection Firefox and other browsers offer. I think it has something to do with http vs https in the address line. We are looking into it and had a similar issue with the old site that Avros corrected. Your information should be safe since basically all you provide is your email address and I doubt we'd ever ask for anything like credit card numbers and such.
Thank you for your patience.
