I agree ssl is a very good thing and getting it hooked up is on my to do list. While an ssl certificate is easy to obtain, it is not easy to get the Discourse configuration I am currently running to work with it. I did look into it and learned of many glitches and errors.
I am planning on re-building the site from scratch at some point and plan to add ssl at that point. Meanwhile do be aware that your password could in theory be sniffed, so stay logged in indefinitely or use a distinct password here.
