I'm really surprised that I haven't received a single response and it has been several days. At any rate, I have answered most of my own questions. Here is where I am at:
I have added:
Code:
$chatname=str_replace(" ", "%20", $bbuserinfo[username]);
$chatpass=$bbuserinfo[password];
$chatroom="General";
to phpinclude. I have created a link EXACTLY as indicated in the instructions. In fact, I've followed all of the instructions. But each time I pass the user name with a space replaced by %20 I am told by phpMyChat that usernames with spaces are not allowed.
I can log into phpMyChat just fine without integration. It works.
What am I missing?
