The security is one thing that has been bothered me. The password is visible in plain text as you log in, not the typical *******. When you go to CCBill to order things the password is there too, meaning AChat actually share your password in plain text with third party companies. I find that quite disturbing. Luckily I cose a password I don't use anywhere else, but if it was one of my standard passwords I'd be quite upset about it.
I think AChat needs to look over the security and privacy arrangements of their software. Things need to be encrypted, having things stored in plain text is not an acceptable option. As the community grows I think this will become even more important.
