To all users, if you have a username with spaces in it, and I mean a clear definitive space without using an underscrore or hyphen, then your username must be changed to include an underscore "_" or hyphen "-" so that it is compatible with the chat system. This is because the chat system uses scripting, and scripting is not conversant to include spaces. This is simply a known web problem, and scripts just don't progress spaces well, so spaces must be removed from usernames to ensure each username is a complete alpha/numeric statement to the script. If you have a username with spaces, expect it to change. New members when you register, if the administrative editors find spaces in your names they will change it to include a hyphen or underscore. Added: Those usernames must be changed regardless, otherwise the forum threads tend to fail during submitting of new posts in that the forum script is caused into an error and shows something like "IM Video chat..." instead of redirecting you directly to the thread again and the post you just made.
