OK...
I have the new v6.2.2 installed in my J!1.7.3 site... and it works FANTASTIC!!!
I have one HUGE question, and I am not sure if it an oversight by me, or something that I may need to core hack...

I have it set that only registered guests can see freichat chatroom and chat. fine, and also just 'buddies' for the chat. NOW... my site is still new-ish, and my 150 members are not too familiar yet with knowing that they should be making 'connections', and I would like to make it easy for them.

So.. can it be done that when people are in the general chatroom, and they are wanting to 'add' that person as a connection, that they could click on their name and it would take them to that person's profile?

Other than that, I am finding it to be FANTASTIC and a HUGE whoop and hollah in your direction!!!

currently that not possible,
FreiChatX was built to run on every possible website, that means Joomla and CB specific features could not be added.
but you can do it with some time & patience. :)

I am sure it's doable... and though I may not have the PURE expertise, but I may be able to if you can point me in the right direction, like which file(s) should I be working with (and maybe which line) so I could then alter/include a line to make the user linked to their profile...

I know its doable but we cannot add it to our distribution since we have to minimize all the platform specific code as much as possible.
there is a function named get_chatroom_users() defined in freichat/server/freichat.php
you will have to modify the HTML/PHP there.
