Alex,
I've been having some conversations with the developer of Invitex (TechJoomla) about integrating their extension with JLinked & JFBConnect. This really means checking for your access session variable being set before Invitex looks for the same. I offered to help them gather whatever information they might need to make this happen.
Would you mind if I was to share a copy of your extension with them? Obviously, I would defer to you on something like this.
Let me know.
Kind regards,
John W.
