In my opinion this option should be enabled by default, it will help to prevent overuse of formatting by inexperienced users( big rainbow effect ) who even don't know how to paste clean text. Also, in my experience pasting of plain text is more often need than pasting of formated text. What do you think guys? Should be this option enabled by default, or at least should forum admins have option to choose the default state?
Rikki , Charles , yes, i understand that messages like "xyz is completely useless" is not helpful. But I did not want to go into details because this topic is dedicated to private messages, not to ip.chat. I could write a more detailed and constructive review of IP.chat problems, but inappropriate in this topic.
