There are no problems found, in view of registring and login to use embedded forumchat, fdikorea. But a thing to note is channel selection.

When you click the menu "register/login and access channel" on left, you have popup, asking " type your name". This popup function is for foruminkorea, default chat channel, which serves forumchat-foruminkorea. That channel is password-locked, registering, login required.

forumchat-fdikorea is password-locked and login is must as well. There is a channel for demonstration, named "demo chat_room", that can be selected in channel list. demo channel is open to the public. No restrictions are there. To use it just click cancel to the popup asking "type your name" and select "demo chat_room" from channel list. Just selection is all that you have to. You are connected just after that selection. But take into account that you may meet Korean words in that channel.

Likewise you can access forumchat-fdikorea. To disregard the default channel, click "cancel" to the popup, and change channel to "for fdikorea.com", and login, put in password. That's it. You may be required to put in new chat name, then create your own one to fill in. The password can be found in calendar for members (you can access it after logging in this fdikorea with member priviledges). The id for fdikorea and that of forumchat is one and another.
