Chat fails for me from my office. Flash does not work here, and I am wondering if there is a way to use the chat system that is entirely html or based on other code (php, javascript..etc) ? The previous version of chat had it's issues I know but whatever codebase it was written in worked everywhere.

this is entirely because the new chat is flash-based, for me. Granted I know that it's not going to affect everyone but I am sure there are a few others that may have problems using flash-based chat systems too.
