But you clicked on a link/button/whatever to chat, so we'd better give you some alternatives to get your chat working. We are using the standard IRC Protocol, as described in the Internet Standard RFC 1459. This means you can use any of the many availiable clients that exist, such as mIRC, BitchX, or ircle (for Windows, unices or mac respectively). Join the server irc.krey.net and join the channel #speurrchat. The channel #speurrchat was the channel the link you followed referred too. If you have any problems running your client, or if you need additional information, you can always visit the Kreynet site which contains all the information needed about our network.
As a last note, every site that uses this script has a return url. The purpose of this script was to open a new popup window using javascript, and then changing the main window to this url: http://www.krey.net. To coninue your visit on the site you were visiting withouth opening the chat, click here.
