I want to create a website with chat rooms and forums. Until now, I have created a website http://siddharth.frih.net/ with forums http://siddharth.frih.net/forum/. I have used mkportal for main page and phpbb for forums. Can any of you advice me the best free chat module for mkportal or phpbb? I do not want for users to have separate ID for chat and forum, it is why I am looking for a chat module, not a indipent chat resourse.
