Here is what I did to test whether the Requests feature seems to be working or not.
1) I set up a small circle of fake Facebook users, using various browsers to keep this straight, and within Facebook and through email got them converted as a circle of Facebook friends.
2) I then went to
www.joomlareview.us, selected Login With Facebook, as one of these users, Veronika. Since there was no existing account I opted to go the create an account function when I got to the Joomla decision window. This worked and I got logged into joomlareview.us as Veronika.
3) I select the JFBConnect Requests link in the right column and got to the requests page/module.
4) I click on the "You are Invited" image and up pops the Facebook window with V's friends.
5) I select a friend, Boris, and click Send Requests. Window goes away swiftly.
6) Then just to see I log into joomlareview.us/administrator, go to JFBConnect component, Requests tab, click on the live Request, click on "See all". The requst I just created is there.
7) Now I return to Facebook, log in as the person who was invited, look for the red notification icon with a number next to it, select it, but other than friends notifications, there is nothing regarding
www.joomlareview.us.
* I have repeated this numerous times with different Facebook users and it is not working or there is something misunderstood by me and my friends about notifications.
