All requests, regardless of whether they were sent as Application or Friend requests, are tracked in JFBConnect. By clicking into the Request in the admin area, you can see the stats for how many times the request has been sent, been acted upon by the receiver, and how many requests have expired. A request expires if it is not acted upon by the user within 14 days of sending it.
There are multiple times that Facebook will not allow the tracking of requests though. In the following cases, a request will not be marked as "Read" even if accepted by the user:
Therefore, the "Read" count should be considered a minimum of the number of Requests that have actually been acted upon.
