I hope this is a joke. It's been happening since I first started posting. It double posts both on Firefox and Chrome. It's not the browsers. It's the server. Occasionally when I post, it takes several seconds to connect back to the domain, and I have made a double post.
As far as the OP goes, I've only been to CACO a few times, after searching something in Google, and the aesthetics of the site turn me off too much for me to even want to register. But, considering this server seems to act up a LOT, I would hope CACO would be more stable.
