@bugicp, Try this plugin https://wordpress.org/extend/plugins/phpfreechat/

@bowromir, Exactly! 🙂

@bugicp, to make it even better, modify the x7chat script to use the bp_user table in the BP database. That way users don’t need to sign in to buddypress and then sign into x7chat.

@bugicp, I know its not recommended but you could just put an iframe on the new page and make the iframe point to the x7chat script.
